p9: avoid unused variable warning

2011-07-26T06:43:53Z

Commit 4e34e719e457 ("fs: take the ACL checks to common code") removed the use of the 'acl' variable in v9fs_iop_get_acl(), but left the variable definition around. Remove it to get rid of the warning: fs/9p/acl.c: In function ‘v9fs_iop_get_acl’: fs/9p/acl.c:101:20: warning: unused variable ‘acl’ Signed-off-by: Linus Torvalds

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

9p: do no return 0 from ->check_acl without actually checking

2011-07-25T18:25:38Z

If we do not want to use ACLs we at least need to perform normal Unix permission checks. From the comment I'm not quite sure that's what is intended, but if 0p wants to do permission checks entirely on the server it needs to do so in ->permission, not in ->check_acl.

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.
