* orangefs: Remove orangefs_backing_dev_infoJan Kara2017-02-031-11/+1

* orangefs: clean up debugfsMike Marshall2016-11-071-2/+4
| | | | | | | | | | | | | | | | | | We recently refactored the Orangefs debugfs code. The refactor seemed to trigger dan.carpenter@oracle.com's static tester to find a possible double-free in the code. While designing the fix we saw a condition under which the buffer being freed could also be overflowed. We also realized how to rebuild the related debugfs file's "contents" (a string) without deleting and re-creating the file. This fix should eliminate the possible double-free, the potential overflow and improve code readability.

* orangefs: rename most remaining global variablesMartin Brandenburg2016-08-161-14/+14
| | | | | | | | Only op_timeout_secs, slot_timeout_secs, and hash_table_size are left because they are exposed as module parameters. All other global variables have the orangefs_ prefix. Signed-off-by: Martin Brandenburg <martin@omnibond.com>

* orangefs: clean up debugfs globalsMartin Brandenburg2016-08-151-51/+2
| | | | | | | | | | Mostly this is moving code into orangefs-debugfs.c so that globals turn into static globals. Then gossip_debug_mask is renamed orangefs_gossip_debug_mask but keeps global visibility, so it can be used from a macro. Signed-off-by: Martin Brandenburg <martin@omnibond.com>

* orangefs: delay freeing slot until cancel completesAl Viro2016-02-191-2/+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).

* Orangefs: clean up slab allocation.Mike Marshall2016-02-041-18/+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>
* orangefs: hopefully saner op refcounting and lockingAl Viro2016-01-231-0/+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>
