Subject: [GIT PULL] overlayfs update for 5.10

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git tags/ovl-update-5.10

- Improve performance for certain container setups by introducing a "volatile"
  mode.

- Ioctl improvements.

- Continue preparation for unprivileged overlay mounts.

Thanks,
Miklos

      ovl: check for incompatible features in work dir
      ovl: support [S|G]ETFLAGS and FS[S|G]ETXATTR ioctls for directories
      ovl: use generic vfs_ioc_setflags_prepare() helper

Miklos Szeredi (9):
      duplicate ovl_getxattr()
      ovl: clean up ovl_getxattr() in copy_up.c
      ovl: fold ovl_getxattr() into ovl_get_redirect_xattr()
      ovl: use ovl_do_getxattr() for private xattr
      ovl: adhere to the vfs_ vs. ovl_do_ conventions for xattrs
      ovl: drop flags argument from ovl_do_setxattr()
      ovl: pass ovl_fs down to functions accessing private xattrs
      ovl: enumerate private xattrs
      ovl: rearrange ovl_can_list()

Vivek Goyal (1):
      ovl: provide a mount option "volatile"
