      audit: optimize audit_compare_dname_path · e3d6b07b
      Jeff Layton authored
      In the cases where we already know the length of the parent, pass it as
      a parm so we don't need to recompute it. In the cases where we don't
      know the length, pass in AUDIT_NAME_FULL (-1) to indicate that it should
      be determined.

      audit: set the name_len in audit_inode for parent lookups · bfcec708
      Jeff Layton authored
      Currently, this gets set mostly by happenstance when we call into
      audit_inode_child. While that might be a little more efficient, it seems
      wrong. If the syscall ends up failing before audit_inode_child ever gets
      called, then you'll have an audit_names record that shows the full path
      but has the parent inode info attached.
      Fix this by passing in a parent flag when we call audit_inode that gets
      set to the value of LOOKUP_PARENT. We can then fix up the pathname for
      the audit entry correctly from the get-go.
      While we're at it, clean up the no-op macro for audit_inode in the

      audit: add a new "type" field to audit_names struct · 78e2e802
      Jeff Layton authored
      For now, we just have two possibilities:
      UNKNOWN: for a new audit_names record that we don't know anything about yet
      NORMAL: for everything else
      In later patches, we'll add other types so we can distinguish and update
      records created under different circumstances.

      audit: reverse arguments to audit_inode_child · c43a25ab
      Jeff Layton authored
      Most of the callers get called with an inode and dentry in the reverse
      order. The compiler then has to reshuffle the arg registers and/or
      stack in order to pass them on to audit_inode_child.
      Reverse those arguments for a micro-optimization.

      audit: no need to walk list in audit_inode if name is NULL · 9cec9d68
      Jeff Layton authored
      If name is NULL then the condition in the loop will never be true. Also,
      with this change, we can eliminate the check for n->name == NULL since
      the equivalence check will never be true if it is.

      vfs: bogus warnings in fs/namei.c · 98f6ef64
      Arnd Bergmann authored
      The follow_link() function always initializes its *p argument,
      or returns an error, but when building with 'gcc -s', the compiler
      gets confused by the __always_inline attribute to the function
      and can no longer detect where the cookie was initialized.
      The solution is to always initialize the pointer from follow_link,
      even in the error path. When building with -O2, this has zero impact
      on generated code and adds a single instruction in the error path
      for a -Os build on ARM.
      Without this patch, building with gcc-4.6 through gcc-4.8 and

      Pull i2c-embedded changes from Wolfram Sang:
       "The changes for i2c-embedded include:
         - massive rework of the omap driver
         - massive rework of the at91 driver.  In fact, the old driver gets
           removed; I am okay with this approach since the old driver was
           depending on BROKEN and its limitations made it practically
           unusable, so people used bitbanging instead.  But even if there are
           users, there is no platform_data or module parameter which would
           need to be converted.  It is just another driver doing I2C
           transfers, just way better.  Modifications of arch/arm/at91 related
           files have proper acks from the maintainer.
         - new driver for R-Car I2C
         - devicetree and generic_clock conversions and fixes
         - usual driver fixes and changes.
        The rework patches have come a long way and lots of people have been
        involved in creating/testing them.  Most patches have been in
        linux-next at least since 3.6-rc5.  A few have been added in the last
        week, I have to admit.
        An unexpected (but welcome :)) peak in private life is the cause for
        that.  The "late" patches shouldn't cause any merge conflicts and I
        will have a special eye on them during the stabilization phase.  This
        is an exception and I want to have the patches in place properly in
        time again for the next kernels."

      autofs4 - fix reset pending flag on mount fail · 49999ab2
      Ian Kent authored
      In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
      mount pending flag is not cleared.
      One effect of this is when using the "browse" option, directory entry
      attributes show up with all "?"s due to the incorrect callback and
      subsequent failure return (when in fact no callback should be made).

      Merge branch 'for-3.7/core' of git://git.kernel.dk/linux-block · ce40be7a
      Linus Torvalds authored
      Pull block IO update from Jens Axboe:
       "Core block IO bits for 3.7.  Not a huge round this time, it contains:
         - First series from Kent cleaning up and generalizing bio allocation
           and freeing.
         - WRITE_SAME support from Martin.
         - Mikulas patches to prevent O_DIRECT crashes when someone changes
           the block size of a device.
         - Make bio_split() work on data-less bio's (like trim/discards).
         - A few other minor fixups."
      Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
      Morton.  It is due to the VM no longer using a prio-tree (see commit
      6b2dbba8: "mm: replace vma prio_tree with an interval tree").
      So make set_blocksize() use mapping_mapped() instead of open-coding the
      internal VM knowledge that has changed.
