Merge branch 'for-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

bf2db0b9 · Linus Torvalds <[email protected]> · 2017-10-06 09:03:08 -07:00

Pull btrfs fixes from David Sterba:
 "Two more fixes for bugs introduced in 4.13.

  The sector_t problem with 32bit architecture and !LBDAF config seems
  serious but the number of affected deployments is hopefully low.

  The clashing status bits could lead to a confusing in-memory state of
  the whole-filesystem operations if used with the quota override sysfs
  knob"

* 'for-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  Btrfs: fix overlap of fs_info::flags values
  btrfs: avoid overflow when sector_t is 32 bit
