Hi Linus, Please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git tags/ovl-update-5.15 - Copy up immutable/append/sync/noatime attributes (Amir Goldstein) - Improve performance by enabling RCU lookup. - Misc fixes and improvements The reason this touches so many files is that the ->get_acl() method now gets a "bool rcu" argument. The ->get_acl() API was updated based on comments from Al and Linus: https://lore.kernel.org/linux-fsdevel/CAJfpeguQxpd6Wgc0Jd3ks77zcsAv_bn0q17L3VNnnmPKu11t8A@xxxxxxxxxxxxxx/ Thanks, Miklos --- Amir Goldstein (5): fs: add generic helper for filling statx attribute flags ovl: pass ovl_fs to ovl_check_setxattr() ovl: copy up sync/noatime fileattr flags ovl: consistent behavior for immutable/append-only inodes ovl: relax lookup error on mismatch origin ftype Chengguang Xu (2): ovl: skip checking lower file's i_writecount on truncate ovl: update ctime when changing fileattr Miklos Szeredi (3): ovl: use kvalloc in xattr copy-up vfs: add rcu argument to ->get_acl() callback ovl: enable RCU'd ->get_acl() Vyacheslav Yurkov (3): ovl: disable decoding null uuid with redirect_dir ovl: add ovl_allow_offline_changes() helper ovl: do not set overlay.opaque for new directories chenying (1): ovl: fix BUG_ON() in may_delete() when called from ovl_cleanup() --- Documentation/filesystems/locking.rst | 2 +- Documentation/filesystems/overlayfs.rst | 3 + Documentation/filesystems/vfs.rst | 2 +- fs/9p/acl.c | 5 +- fs/9p/acl.h | 2 +- fs/bad_inode.c | 2 +- fs/btrfs/acl.c | 5 +- fs/btrfs/ctree.h | 2 +- fs/ceph/acl.c | 5 +- fs/ceph/super.h | 2 +- fs/erofs/xattr.c | 5 +- fs/erofs/xattr.h | 2 +- fs/ext2/acl.c | 5 +- fs/ext2/acl.h | 2 +- fs/ext4/acl.c | 5 +- fs/ext4/acl.h | 2 +- fs/f2fs/acl.c | 5 +- fs/f2fs/acl.h | 2 +- fs/fuse/acl.c | 5 +- fs/fuse/fuse_i.h | 2 +- fs/gfs2/acl.c | 5 +- fs/gfs2/acl.h | 2 +- fs/jffs2/acl.c | 5 +- fs/jffs2/acl.h | 2 +- fs/jfs/acl.c | 5 +- fs/jfs/jfs_acl.h | 2 +- fs/nfs/nfs3_fs.h | 2 +- fs/nfs/nfs3acl.c | 5 +- fs/ocfs2/acl.c | 5 +- fs/ocfs2/acl.h | 2 +- fs/orangefs/acl.c | 5 +- fs/orangefs/inode.c | 7 +-- fs/orangefs/orangefs-kernel.h | 2 +- fs/overlayfs/copy_up.c | 83 ++++++++++++++++++++----- fs/overlayfs/dir.c | 16 +++-- fs/overlayfs/inode.c | 105 +++++++++++++++++++++++++------- fs/overlayfs/namei.c | 4 +- fs/overlayfs/overlayfs.h | 44 +++++++++++-- fs/overlayfs/super.c | 4 +- fs/overlayfs/util.c | 92 ++++++++++++++++++++++++++-- fs/posix_acl.c | 15 ++++- fs/reiserfs/acl.h | 2 +- fs/reiserfs/xattr_acl.c | 5 +- fs/stat.c | 18 ++++++ fs/xfs/xfs_acl.c | 5 +- fs/xfs/xfs_acl.h | 4 +- include/linux/fs.h | 8 ++- include/linux/posix_acl.h | 3 +- include/linux/stat.h | 4 ++ 49 files changed, 424 insertions(+), 102 deletions(-)
