#     Merge tag 'ovl-update-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
#     
#     Pull overlayfs updates from Miklos Szeredi:
#     
#      - Improve performance for certain container setups by introducing a
#        "volatile" mode
#     
#      - ioctl improvements
#     
#      - continue preparation for unprivileged overlay mounts
#     
#     * tag 'ovl-update-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
#       ovl: use generic vfs_ioc_setflags_prepare() helper
#       ovl: support [S|G]ETFLAGS and FS[S|G]ETXATTR ioctls for directories
#       ovl: rearrange ovl_can_list()
#       ovl: enumerate private xattrs
#       ovl: pass ovl_fs down to functions accessing private xattrs
#       ovl: drop flags argument from ovl_do_setxattr()
#       ovl: adhere to the vfs_ vs. ovl_do_ conventions for xattrs
#       ovl: use ovl_do_getxattr() for private xattr
#       ovl: fold ovl_getxattr() into ovl_get_redirect_xattr()
#       ovl: clean up ovl_getxattr() in copy_up.c
#       duplicate ovl_getxattr()
#       ovl: provide a mount option "volatile"
#       ovl: check for incompatible features in work dir
