      kernfs: drop s_ prefix from kernfs_node members · adc5e8b5
      Tejun Heo authored
      
      
      kernfs has just been separated out from sysfs and we're already in
      full conflict mode.  Nothing can make the situation any worse.  Let's
      take the chance to name things properly.
      
      s_ prefix for kernfs members is used inconsistently and a misnomer
      now.  It's not like kernfs_node is used widely across the kernel
      making the ability to grep for the members particularly useful.  Let's
      just drop the prefix.
      
      This patch is strictly rename only and doesn't introduce any
      functional difference.

      kernfs: s/sysfs_dirent/kernfs_node/ and rename its friends accordingly · 324a56e1

      kernfs has just been separated out from sysfs and we're already in
      full conflict mode.  Nothing can make the situation any worse.  Let's
      take the chance to name things properly.
      
      This patch performs the following renames.
      
      * s/sysfs_elem_dir/kernfs_elem_dir/
      * s/sysfs_elem_symlink/kernfs_elem_symlink/
      * s/sysfs_elem_attr/kernfs_elem_file/
      * s/sysfs_dirent/kernfs_node/
      * s/sd/kn/ in kernfs proper
      * s/parent_sd/parent/
      * s/target_sd/target/
      * s/dir_sd/parent/
      * s/to_sysfs_dirent()/rb_to_kn()/
      * misc renames of local vars when they conflict with the above
      
      Because md, mic and gpio dig into sysfs details, this patch ends up
      modifying them.  All are sysfs_dirent renames and trivial.  While we
      can avoid these by introducing a dummy wrapping struct sysfs_dirent
      around kernfs_node, given the limited usage outside kernfs and sysfs
      proper, I don't think such workaround is called for.
      
      This patch is strictly rename only and doesn't introduce any
      functional difference.
      
      - mic / gpio renames were missing.  Spotted by kbuild test robot.

      After realizing that we tend to tell developers the same thing over
      and over, let's attempt to document some commin design patterns
      used in the device drivers. The idea is that this can be extended
      so I just start out with two well-known design patterns.

      While restructuring the [u]mount path, 4b93dc9b
      
       ("sysfs, kernfs:
      prepare mount path for kernfs") incorrectly updated sysfs_kill_sb() so
      that it first kills super_block and then tries to dereference its
      namespace tag to drop it.  Fix it by caching namespace tag before
      killing the superblock and then drop the cached namespace tag.

      sysfs: bail early from kernfs_file_mmap() to avoid spurious lockdep warning · 9b2db6e1
      Tejun Heo authored
      This is v3.14 fix for the same issue that a8b14744 ("sysfs: give
      different locking key to regular and bin files") addresses for v3.13.
      Due to the extensive kernfs reorganization in v3.14 branch, the same
      fix couldn't be ported as-is.  The v3.13 fix was ignored while merging
      it into v3.14 branch.
      
      027a485d ("sysfs: use a separate locking class for open files
      depending on mmap") assigned different lockdep key to
      sysfs_open_file->mutex depending on whether the file implements mmap
      or not in an attempt to avoid spurious lockdep warning caused by
      merging of regular and bin file paths.
      
      While this restored some of the original behavior of using different
      locks (at least lockdep is concerned) for the different clases of
      files.  The restoration wasn't full because now the lockdep key
      assignment depends on whether the file has mmap or not instead of
      whether it's a regular file or not.
      
      This means that bin files which don't implement mmap will get assigned
      the same lockdep class as regular files.  This is problematic because
      file_operations for bin files still implements the mmap file operation
      and checking whether the sysfs file actually implements mmap happens
      in the file operation after grabbing @sysfs_open_file->mutex.  We
      still end up adding locking dependency from mmap locking to
      sysfs_open_file->mutex to the regular file mutex which triggers
      spurious circular locking warning.
      
      For v3.13, a8b14744
      
       ("sysfs: give different locking key to regular
      and bin files") fixed it by giving sysfs_open_file->mutex different
      lockdep keys depending on whether the file is regular or bin instead
      of whether mmap exists or not; however, due to the way sysfs is now
      layered behind kernfs, this approach is no longer viable.  kernfs can
      tell whether a sysfs node has mmap implemented or not but can't tell
      whether a bin file from a regular one.
      
      This patch updates kernfs such that kernfs_file_mmap() checks
      SYSFS_FLAG_HAS_MMAP and bail before grabbing sysfs_open_file->mutex so
      that it doesn't add spurious locking dependency from mmap to
      sysfs_open_file->mutex and changes sysfs so that it specifies
      kernfs_ops->mmap iff the sysfs file implements mmap.  Combined, this
      ensures that sysfs_open_file->mutex is grabbed under mmap path iff the
      sysfs file actually implements mmap.  As sysfs_open_file->mutex is
      already given a different lockdep key if mmap is implemented, this
      removes the spurious locking dependency.

      Merge branch 'driver-core-linus' into driver-core-next · 13ccb93f
      Tejun Heo authored
      a8b14744
      
       ("sysfs: give different locking key to regular and bin
      files") in driver-core-linus modifies sysfs_open_file() so that it
      gives out different locking classes to sysfs_open_files depending on
      whether the file is bin or not.  Due to the massive kernfs
      reorganization in driver-core-next, this naturally causes merge
      conflict in fs/sysfs/file.c.
      
      Due to the way things are split between kernfs and sysfs in
      driver-core-next, the same fix can't easily be applied to
      driver-core-next.  This merge simply ignores the offending commit.  A
      following patch will implement a separate fix for the issue.

      kobject: remove kset from sysfs immediately in kset_unregister() · 35a5fe69
      Bjorn Helgaas authored
      
      
      There's no "unlink from sysfs" interface for ksets, so I think callers of
      kset_unregister() expect the kset to be removed from sysfs immediately,
      without waiting for the last reference to be released.
      
      This patch makes the sysfs removal happen immediately, so the caller may
      create a new kset with the same name as soon as kset_unregister() returns.
      Without this, every caller has to call "kobject_del(&kset->kobj)" first
      unless it knows it will never create a new kset with the same name.
      
      This sometimes shows up on module unload and reload, where the reload fails
      because it tries to create a kobject with the same name as one from the
      original load that still exists.  CONFIG_DEBUG_KOBJECT_RELEASE=y makes this
      problem easier to hit.

       "A regression showed up that there's a large delay when enabling all

        enables all events several times, and caused the system bootup to
        pause for over a minute.
      
        This was tracked down to an addition of a synchronize_sched()
        performed when system call tracepoints are unregistered.
      
        The synchronize_sched() is needed between the unregistering of the
        system call tracepoint and a deletion of a tracing instance buffer.
        But placing the synchronize_sched() in the unreg of *every* system
        call tracepoint is a bit overboard.  A single synchronize_sched()
        before the deletion of the instance is sufficient"

      tracing: Only run synchronize_sched() at instance deletion time · 3ccb0123
      Steven Rostedt authored
      It has been reported that boot up with FTRACE_SELFTEST enabled can take a
      very long time. There can be stalls of over a minute.
      
      This was tracked down to the synchronize_sched() called when a system call
      event is disabled. As the self tests enable and disable thousands of events,
      this makes the synchronize_sched() get called thousands of times.
      
      The synchornize_sched() was added with d562aff9 "tracing: Add support
      for SOFT_DISABLE to syscall events" which caused this regression (added
      in 3.13-rc1).
      
      The synchronize_sched() is to protect against the events being accessed
      when a tracer instance is being deleted. When an instance is being deleted
      all the events associated to it are unregistered. The synchronize_sched()
      makes sure that no more users are running when it finishes.
      
      Instead of calling synchronize_sched() for all syscall events, we only
      need to call it once, after the events are unregistered and before the
      instance is deleted. The event_mutex is held during this action to
      prevent new users from enabling events.

      Linus Torvalds authored
      Pull x86 and EFI fixes from Peter Anvin:
       "Half of these are EFI-related:
      
        The by far biggest change is the change to hold off the deletion of a
        sysfs entry while a backend scan is in progress.  This is to avoid
        calling kmemdup() while under a spinlock.
      
        The other major change is for each entry in the EFI pstore backend to
        get a unique identifier, as required by the pstore filesystem proper.
      
        The other changes are:
      
        A fix to the recent consolidation and optimization of using "asm goto"
        with read-modify-write operation, which broke the bitops; specifically
        in such a way that we could end up generating invalid code.
      
        A build hack to make sure we compile with -mno-sse.  icc, and most
        likely future versions of gcc, can generate SSE instructions unless we
        tell it not to.
      
        A comment-only patch to a change the was due in part to an unpublished
        erratum; now when the erratum is published we want to add a comment
        explaining why"
