Subject: [PATCH 7/8] posix acls: Export xattr_handler functions
Date: Thu, 14 Apr 2016 00:27:45 +0200 [thread overview]
Message-ID: <1460586466-5518-8-git-send-email-agruenba@redhat.com> (raw)
In-Reply-To: <1460586466-5518-1-git-send-email-agruenba@redhat.com>
In-Reply-To: <20160413182026.GR25498@ZenIV.linux.org.uk>
These functions are useful in filesystems like gfs2 which require
pre-/postamble code around xattr operations.
