# Merge: b28866f4bb77 80e5d1ff5d5f
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun May 2 09:14:01 2021 -0700
# 
#     Merge branch 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull misc vfs updates from Al Viro:
#      "Assorted stuff all over the place"
#     
#     * 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       useful constants: struct qstr for ".."
#       hostfs_open(): don't open-code file_dentry()
#       whack-a-mole: kill strlen_user() (again)
#       autofs: should_expire() argument is guaranteed to be positive
#       apparmor:match_mn() - constify devpath argument
#       buffer: a small optimization in grow_buffers
#       get rid of autofs_getpath()
#       constify dentry argument of dentry_path()/dentry_path_raw()
