2016-02-19orangefs: delay freeing slot until cancel completesAl Viro1-2/+0
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).

2016-02-04Orangefs: clean up slab allocation.Mike Marshall1-18/+2
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: Mike Marshall <hubcap@omnibond.com>
2016-01-23orangefs: hopefully saner op refcounting and lockingAl Viro1-0/+2
* 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: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
