* checking that daemon is running (to decide whether we want to limit the timeout) should be done *after* the damn thing is included into the list; doing that before means that if the daemon gets shut down in between, we'll end up waiting indefinitely (== up to kill -9). * cancels should go into the head of the queue - the sooner they are picked, the less work daemon has to do and the sooner we get to free the slot held by aborted operation.

Make cancels reuse the aborted read/write op, to make sure they do not fail on lack of memory. Don't issue a cancel unless the daemon has seen our read/write, has not replied and isn't being shut down. If cancel *is* issued, don't wait for it to complete; stash the slot in there and just have it freed when cancel is finally replied to or purged (and delay dropping the reference until then, obviously).

Thus d_revalidate is not obliged to check on as much, which will eventually lead the way to hammering the filesystem servers much less. Signed-off-by:

A couple of caches were no longer needed: - iov_iter improvements to orangefs_devreq_write_iter eliminated the need for the dev_req_cache. - removal (months ago) of the old AIO code eliminated the need for the kiocb_cache. Also, deobfuscation of use of GFP_KERNEL when calling kmem_cache_(z)alloc for remaining caches. Signed-off-by: -

There were two just alike, making it hard maybe to tell which one you were looking at in syslog... so I changed it a little by adding some extra interesting tidbits to it... Signed-off-by:

Previously, it would update a live inode. This was fixed, but it did not ever check that the inode attributes in the dcache are correct. This checks all inode attributes and rejects any that are not correct, which causes a lookup and thus a new getattr. Perhaps inode_operations->permission should replace or augment some of this. There is no actual caching, and this does a rather excessive amount of network operations back to the filesystem server. Signed-off-by:

* create with refcount 1 * make op_release() decrement and free if zero (i.e. old put_op() has become that). * mark when submitter has given up waiting; from that point nobody else can move between the lists, change state, etc. * have daemon read/write_iter grab a reference when picking op and *always* give it up in the end * don't put into hash until we know it's been successfully passed to daemon * move op->lock _lower_ than htab_in_progress_lock (and make sure to take it in purge_inprogress_ops()) Signed-off-by:
