Subject: [PATCH 05/18] fs: make posix_acl_chmod more useful
Date: Sun, 01 Dec 2013 03:59:08 -0800 [thread overview]
Message-ID: <20131201120654.453220050@bombadil.infradead.org> (raw)
In-Reply-To: 20131201115903.910559036@bombadil.infradead.org
[-- Attachment #1: 0005-fs-make-posix_acl_chmod-more-useful.patch --]
[-- Type: text/plain, Size: 10566 bytes --]
Rename the current posix_acl_chmod to __posix_acl_chmod and add
a fully featured ACL chmod helper that uses the ->set_acl inode
operation.
