2010-05-17	ceph: all allocation functions should get gfp_mask	Yehuda Sadeh	1	-2/+2
	This is essential, as for the rados block device we'll need to run in different contexts that would need flags that are other than GFP_NOFS. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17	ceph: name msgpools; useful error messages	Sage Weil	1	-4/+9
	Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17	ceph: simplify ceph_msg_new	Sage Weil	1	-2/+2
	We only need to pass in front_len. Callers can attach any other payload pieces (middle, data) as they see fit. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17	ceph: make ceph_msg_new return NULL on failure; clean up, fix callers	Sage Weil	1	-11/+2
	Returning ERR_PTR(-ENOMEM) is useless extra work. Return NULL on failure instead, and fix up the callers (about half of which were wrong anyway). Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17	ceph: rewrite msgpool using mempool_t	Sage Weil	1	-145/+27
	Since we don't need to maintain large pools of messages, we can just use the standard mempool_t. We maintain a msgpool 'wrapper' because we need the mempool_t* in the alloc function, and mempool gives us only pool_data. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17	ceph: update for removal of kref_set	Stephen Rothwell	1	-1/+1
	Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Sage Weil <sage@newdream.net>
2010-03-01	ceph: reset front len on return to msgpool; BUG on mismatched front iov	Sage Weil	1	-0/+4
	Reset msg front len when a message is returned to the pool: the caller may have changed it. BUG if we try to send a message with a hdr.front_len that doesn't match the front iov. Signed-off-by: Sage Weil <sage@newdream.net>
2009-12-23	ceph: more informative msgpool errors	Sage Weil	1	-1/+2
	Signed-off-by: Sage Weil <sage@newdream.net>
2009-12-07	ceph: use kref for ceph_msg	Sage Weil	1	-1/+1
	Signed-off-by: Sage Weil <sage@newdream.net>
2009-10-15	ceph: warn on allocation from msgpool with larger front_len	Sage Weil	1	-3/+17
	Pass the front_len we need when pulling a message off a msgpool, and WARN if it is greater than the pool's size. Then try to allocate a new message (to continue without failing). Signed-off-by: Sage Weil <sage@newdream.net>
2009-10-06	ceph: message pools	Sage Weil	1	-0/+167
	The msgpool is a basic mempool_t-like structure to preallocate messages we expect to receive over the wire. This ensures we have the necessary memory preallocated to process replies to requests, or to process unsolicited messages from various servers. Signed-off-by: Sage Weil <sage@newdream.net>
