Subject: [Ocfs2-devel] forget_all_cached_acls()
Date: Tue, 22 Feb 2011 01:32:13 -0800 [thread overview]
Message-ID: <20110222093212.GF30966@noexit> (raw)
Hey everyone,
I just found out from Steven over in GFS2 that there is a kernel
call forget_all_cached_acls(). If a cluster filesystem is using ACL
caching (added by Viro a little while back), they use
forget_all_cached_acls() at lock drop time to make sure they don't have
stale ACL info.
We're not using cached_acls yet, but if someone adds it, please
remember this call ;-)
Joel
