ceph: initialize root dentry

2011-11-11T17:50:17+00:00

Set up d_fsdata on the root dentry.  This fixes a NULL pointer dereference
in ceph_d_prune on umount.  It also means we can eventually strip out all
of the conditional checks on d_fsdata because it is now set unconditionally
(prior to setting up the d_ops).

Fix the ceph_d_prune debug print while we're here.

ceph: fix iput race when queueing inode work

2011-11-06T05:06:31+00:00

If we queue a work item that calls iput(), make sure we ihold() before
attempting to queue work. Otherwise our queued work might miraculously run
before we notice the queue_work() succeeded and call ihold(), allowing the
inode to be destroyed.

That is, instead of

	if (queue_work(...))
		ihold();

we need to do

	ihold();
	if (!queue_work(...))
		iput();

ceph/mds_client.c: quiet sparse noise

2011-11-06T04:10:11+00:00

Quiet the following sparse noise:

warning: symbol 'get_nonsnap_parent' was not declared. Should it be static?
warning: symbol 'done_closing_sessions' was not declared. Should it be static?

Local functions don't need external visability. Make them static.

ceph: use new D_COMPLETE dentry flag

2011-11-06T04:10:10+00:00

We used to use a flag on the directory inode to track whether the dcache
contents for a directory were a complete cached copy.  Switch to a dentry
flag CEPH_D_COMPLETE that is safely updated by ->d_prune().

ceph: clear parent D_COMPLETE flag when on dentry prune

2011-11-03T16:23:49+00:00

When the VFS prunes a dentry from the cache, clear the D_COMPLETE flag
on the parent dentry.  Do this for the live and snapshotted namespaces. Do
not bother for the .snap dir contents, since we do not cache that.

ceph: let the set_layout ioctl set single traits

2011-10-25T23:10:16+00:00

Previously we were validating the passed-in stripe unit, object size,
and stripe count against each other (and not testing most other stuff).
Instead, make sure that the composed previous layout and new values are valid,
and only send the new values to the MDS. This lets users change the
pool without setting the whole layout, for instance.
