 "Assorted VFS fixes and related cleanups (IMO the most interesting in
  that part are f_path-related things and Eric's descriptor-related
  stuff).  UFS regression fixes (it got broken last cycle).  9P fixes.
  fs-cache series, DAX patches, Jan's file_remove_suid() work"

[ I'd say this is much more than "fixes and related cleanups".  The
  file_table locking rule change by Eric Dumazet is a rather big and
  fundamental update even if the patch isn't huge.   - Linus ]

Pull MTD updates from Brian Norris:
 "JFFS2:
   - fix a theoretical unbalanced locking issue; the lock handling was a
     bit unclean, but AFAICT, it didn't actually lead to real deadlocks

  NAND:
   - brcmnand driver: new driver supporting NAND controller found
     originally on Broadcom STB SoCs (BCM7xxx), but now also found on
     BCM63xxx, iProc (e.g., Cygnus, BCM5301x), BCM3xxx, and more

   - begin factoring out BBT code so it can be shared between
     traditional (parallel) NAND drivers and upcoming SPI NAND drivers
     (WIP)

   - add common DT-based init support, so nand_base can pick up some
     flash properties automatically, using established common NAND DT
     properties

   - mxc_nand: support 8-bit ECC

   - pxa3xx_nand:
     * fix build for ARM64
     * use a jiffies-based timeout

  SPI NOR:
   - add a few new IDs

   - clear out some unnecessary entries

   - make sure SECT_4K flags are correct for all (?) entries

  Core:
   - fix mtd->usecount race conditions (BUG_ON())

   - switch to modern PM ops

  Other:
   - CFI: save code space by de-inlining large functions

   - clean up some partition parser selection code across several
     drivers

   - various miscellaneous changes, mostly minor"

list_entry is just a wrapper for container_of, but it is arguably
wrong (and slightly confusing) to use it when the pointed-to struct
member is not a struct list_head. Use container_of directly instead.

Li Zefan reported an unbalanced locking issue, found by his
internal debugging feature on runtime. The particular case he was
looking at doesn't lead to a deadlock, as the structure that this lock
is embedded in is freed on error. But we should straighten out the error
handling.

Because several callers of jffs2_do_read_inode_internal() /
jffs2_do_read_inode() already handle the locking/unlocking and inode
clearing at their own level, let's just push any unlocks/clearing down
to the caller. This consistency is much easier to verify.

Pull MTD updates from Brian Norris:
 "Common MTD:

   - Add Kconfig option for keeping both the 'master' and 'partition'
     MTDs registered as devices.  This would really make a better
     default if we could do it over, as it allows a lot more flexibility
     in (1) determining the flash topology of the system from user-space
     and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

     Unfortunately, this would possibly cause user-space breakage, as it
     will cause renumbering of the /dev/mtdX devices.  We'll see if we
     can change this in the future, as there have already been a few
     people looking for this feature, and I know others have just been
     working around our current limitations instead of fixing them this
     way.

   - Along with the previous change, add some additional information to
     sysfs, so user-space can read the offset of each partition within
     its master device

  SPI NOR:

   - add new device tree compatible binding to represent the
     mostly-compatible class of SPI NOR flash which can be detected by
     their extended JEDEC ID bytes, cutting down the duplication of our
     ID tables

   - misc.  new IDs

  Various other miscellaneous fixes and changes"
