      Pull XFS updates from Darrick Wong:
       "Here are the changes for xfs for 4.14. Most of these are cleanups and
        fixes for bad behavior, as we're mostly focusing on improving
        reliablity this cycle (read: there's potentially a lot of stuff on the
        horizon for 4.15 so better to spend a few weeks killing other bugs
        now).
      
        Summary:
      
         - Write unmount record for a ro mount to avoid unnecessary log replay
      
         - Clean up orphaned inodes when mounting fs readonly

         - Avoid infinite loop searching for free inodes when inode counters
           are wrong
      
         - Evict inodes involved with log redo so that we don't leak them
           later
      
         - Fix a potential race between reclaim and inode cluster freeing
      
         - Refactor the inode joining code w.r.t. transaction rolling &
           deferred ops
      
         - Fix a bug where the log doesn't properly deal with dirty buffers
           that are about to become ordered buffers
      
         - Fix the extent swap code to deal with making dirty buffers ordered
           properly
      
         - Consolidate page fault handlers
      
         - Refactor the incore extent manipulation functions to use the iext
           abstractions instead of directly modifying with extent data
      
         - Disable crashy chattr +/-x until we fix it
      
         - Don't allow us to set S_DAX for v2 inodes
      
         - Various cleanups
      
         - Clarify some documentation
      
         - Fix a problem where fsync and a log commit race to send the disk a
           flush command, resulting in a small window where power fail data
           loss could occur
      
         - Simplify some rmap operations in the fcollapse code
      
         - Fix some use-after-free problems in async writeback"

      Linus Torvalds authored
      Pull GFS2 updates from Bob Peterson:
       "We've got a whopping 29 GFS2 patches for this merge window, mainly
        because we held some back from the previous merge window until we
        could get them perfected and well tested. We have a couple patch sets,
        including my patch set for protecting glock gl_object and Andreas
        Gruenbacher's patch set to fix the long-standing shrink- slab hang,
        plus a bunch of assorted bugs and cleanups.
      
        Summary:
      
         - I fixed a bug whereby an IO error would lead to a double-brelse.
      
         - Andreas Gruenbacher made a minor cleanup to call his relatively new
           function, gfs2_holder_initialized, rather than doing it manually.
           This was just missed by a previous patch set.
      
         - Jan Kara fixed a bug whereby the SGID was being cleared when
           inheriting ACLs.
      
         - Andreas found a bug and fixed it in his previous patch, "Get rid of
           flush_delayed_work in gfs2_evict_inode". A call to
           flush_delayed_work was deleted from *gfs2_inode_lookup and added to
           gfs2_create_inode.
      
         - Wang Xibo found and fixed a list_add call in inode_go_lock that
           specified the parameters in the wrong order.
      
         - Coly Li submitted a patch to add the REQ_PRIO to some of GFS2's
           metadata reads that were accidentally missing them.
      
         - I submitted a 4-patch set to protect the glock gl_object field.
           GFS2 was setting and checking gl_object with no locking mechanism,
           so the value was occasionally stomped on, which caused file system
           corruption.
      
         - I submitted a small cleanup to function gfs2_clear_rgrpd. It was
           needlessly adding rgrp glocks to the lru list, then pulling them
           back off immediately. The rgrp glocks don't use the lru list
           anyway, so doing so was just a waste of time.
      
         - I submitted a patch that checks the GLOF_LRU flag on a glock before
           trying to remove it from the lru_list. This avoids a lot of
           unnecessary spin_lock contention.
      
         - I submitted a patch to delete GFS2's debugfs files only after we
           evict all the glocks. Before this patch, GFS2 would delete the
           debugfs files, and if unmount hung waiting for a glock, there was
           no way to debug the problem. Now, if a hang occurs during umount,
           we can examine the debugfs files to figure out why it's hung.
      
         - Andreas Gruenbacher submitted a patch to fix some trivial typos.
      
         - Andreas also submitted a five-part patch set to fix the
           longstanding hang involving the slab shrinker: dlm requires memory,
           calls the inode shrinker, which calls gfs2's evict, which calls
           back into DLM before it can evict an inode.
      
         - Abhi Das submitted a patch to forcibly flush the active items list
           to relieve memory pressure. This fixes a long-standing bug whereby
           GFS2 was getting hung permanently in balance_dirty_pages.
      
         - Thomas Tai submitted a patch to fix a slab corruption problem due
           to a residual pointer left in the lock_dlm lockstruct.
      
         - I submitted a patch to withdraw the file system if IO errors are
           encountered while writing to the journals or statfs system file
           which were previously not being sent back up. Before, some IO
           errors were sometimes not be detected for several hours, and at
           recovery time, the journal errors made journal replay impossible.
      
         - Andreas has a patch to fix an annoying format-truncation compiler
           warning so GFS2 compiles cleanly.
      
         - I have a patch that fixes a handful of sparse compiler warnings.
      
         - Andreas fixed up an useless gl_object warning caused by an earlier
           patch.
      
         - Arvind Yadav added a patch to properly constify our rhashtable
           params declare.
      
         - I added a patch to fix a regression caused by the non-recursive
           delete and truncate patch that caused file system blocks to not be
           properly freed.
      
         - Ernesto A. Fernández added a patch to fix a place where GFS2 would
           send back the wrong return code setting extended attributes.
      
         - Ernesto also added a patch to fix a case in which GFS2 was
           improperly setting an inode's i_mode, potentially granting access
           to the wrong users"

      mac80211: fix deadlock in driver-managed RX BA session start · bde59c47
      Johannes Berg authored
      When an RX BA session is started by the driver, and it has to tell
      mac80211 about it, the corresponding bit in tid_rx_manage_offl gets
      set and the BA session work is scheduled. Upon testing this bit, it
      will call __ieee80211_start_rx_ba_session(), thus deadlocking as it
      already holds the ampdu_mlme.mtx, which that acquires again.
      
      Fix this by adding ___ieee80211_start_rx_ba_session(), a version of
      the function that requires the mutex already held.

      mac80211: Complete ampdu work schedule during session tear down · 98e93e96

      Commit 7a7c0a64
      
       ("mac80211: fix TX aggregation start/stop callback race")
      added a cancellation of the ampdu work after the loop that stopped the
      Tx and Rx BA sessions. However, in some cases, e.g., during HW reconfig,
      the low level driver might call mac80211 APIs to complete the stopping
      of the BA sessions, which would queue the ampdu work to handle the actual
      completion. This work needs to be performed as otherwise mac80211 data
      structures would not be properly synced.
      
      Fix this by checking if BA session STOP_CB bit is set after the BA session
      cancellation and properly clean the session.

      [Johannes: the work isn't flushed because that could do other things we
       don't want, and the locking situation isn't clear]

      cfg80211: honor NL80211_RRF_NO_HT40{MINUS,PLUS} · 4e0854a7

      Honor the NL80211_RRF_NO_HT40{MINUS,PLUS} flags in
      reg_process_ht_flags_channel. Not doing so leads can lead
      to a firmware assert in iwlwifi for example.

      ====================
      Intel Wired LAN Driver Updates 2017-09-05
      
      This series contains fixes for i40e only.
      
      These two patches fix an issue where our nvmupdate tool does not work on RHEL 7.4
      and newer kernels, in fact, the use of the nvmupdate tool on newer kernels can
      cause the cards to be non-functional unless these patches are applied.
      
      Anjali reworks the locking around accessing the NVM so that NVM acquire timeouts
      do not occur which was causing the failed firmware updates.
      
      Jake correctly updates the wb_desc when reading the NVM through the AdminQ.
