# commit f359287765c04711ff54fbd11645271d8e5ff763
# Merge: 8b39a57e9654 c8ffd8bcdd28
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Jun 1 16:44:06 2020 -0700
# 
#     Merge branch 'from-miklos' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull vfs updates from Al Viro:
#      "Assorted patches from Miklos.
#     
#       An interesting part here is /proc/mounts stuff..."
#     
#     The "/proc/mounts stuff" is using a cursor for keeeping the location
#     data while traversing the mount listing.
#     
#     Also probably worth noting is the addition of faccessat2(), which takes
#     an additional set of flags to specify how the lookup is done
#     (AT_EACCESS, AT_SYMLINK_NOFOLLOW, AT_EMPTY_PATH).
#     
#     * 'from-miklos' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       vfs: add faccessat2 syscall
#       vfs: don't parse "silent" option
#       vfs: don't parse "posixacl" option
#       vfs: don't parse forbidden flags
#       statx: add mount_root
#       statx: add mount ID
#       statx: don't clear STATX_ATIME on SB_RDONLY
#       uapi: deprecate STATX_ALL
#       utimensat: AT_EMPTY_PATH support
#       vfs: split out access_override_creds()
#       proc/mounts: add cursor
#       aio: fix async fsync creds
#       vfs: allow unprivileged whiteout creation
