Btrfs: fix return value of btrfs_get_acl()

2011-10-20T16:10:47Z

In btrfs_get_acl(), when the second __btrfs_getxattr() call fails, acl is not correctly set. Therefore, a wrong value might return to the caller. Signed-off-by: Tsutomu Itoh

Btrfs: make acl functions really no-op if acl is not enabled

So there's no overhead for something we don't use. Signed-off-by: Li Zefan Signed-off-by: Chris Mason

fs: take the ACL checks to common code

2011-07-25T18:30:23Z

Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

kill boilerplates around posix_acl_create_masq()

2011-07-25T18:27:32Z

new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with modified clone, on failure releases acl and replaces with NULL. Returns 0 or -ve on error. All callers of posix_acl_create_masq() switched. Signed-off-by: Al Viro

kill boilerplate around posix_acl_chmod_masq()

2011-07-25T18:27:30Z

new helper: posix_acl_chmod(&acl, gfp, mode). Replaces acl with modified clone or with NULL if that has failed; returns 0 or -ve on error. All callers of posix_acl_chmod_masq() switched to that - they'd been doing exactly the same thing. Signed-off-by: Al Viro

vfs: move ACL cache lookup into generic code

2011-07-25T18:23:39Z

This moves logic for checking the cached ACL values from low-level filesystems into generic code. The end result is a streamlined ACL check that doesn't need to load the inode->i_op->check_acl pointer at all for the common cached case. The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.
