      ata: ahci: find eSATA ports and flag them as removable · 8a3e33cf
      Manuel Lauss authored
      If the AHCI ports' HPCP or ESP bits are set, the port
      should be considered external (e.g. eSATA) and is marked
      as removable.  Userspace tools like udisks then treat it
      like an usb drive.
      
      With this patch applied, when I plug a drive into the esata port,
      KDE pops up a window asking what to do with the drives(s), just
      like it does for any random USB stick.
      
      Removability is indicated to the upper layers by way of the
      SCSI RMB bit, as I haven't found another way to signal
      userspace to treat a sata disk like any usb stick.

      NFSv4: Respect the server imposed limit on how many changes we may cache · 5445b1fb
      Trond Myklebust authored
      The NFSv4 delegation spec allows the server to tell a client to limit how
      much data it cache after the file is closed. In return, the server
      guarantees enough free space to avoid ENOSPC situations, etc.
      Prior to this patch, we assumed we could always cache aggressively after
      close. Unfortunately, this causes problems with servers that set the
      limit to 0 and therefore do not offer any ENOSPC guarantees.

      Since we're tracking modifications to the page cache on a per-page

      Merge branch 'akpm' (patches from Andrew) · 6c0f568e
      Linus Torvalds authored
      Merge patch-bomb from Andrew Morton:
      
       - a few misc things
      
       - Andy's "ambient capabilities"
      
       - fs/nofity updates
      
       - the ocfs2 queue
      
       - kernel/watchdog.c updates and feature work.
      
       - some of MM.  Includes Andrea's userfaultfd feature.
      
      [ Hadn't noticed that userfaultfd was 'default y' when applying the
        patches, so that got fixed in this merge instead.  We do _not_ mark
        new features that nobody uses yet 'default y'   - Linus ]

      task_work: remove fifo ordering guarantee · c8219906
      Eric Dumazet authored
      In commit f341861f ("task_work: add a scheduling point in
      task_work_run()") I fixed a latency problem adding a cond_resched()
      call.
      
      Later, commit ac3d0da8 added yet another loop to reverse a list,
      bringing back the latency spike :
      
      I've seen in some cases this loop taking 275 ms, if for example a
      process with 2,000,000 files is killed.
      
      We could add yet another cond_resched() in the reverse loop, or we
      can simply remove the reversal, as I do not think anything
      would depend on order of task_work_add() submitted works.
      
      Fixes: ac3d0da8 ("task_work: Make task_work_add() lockless")
