2025-05-14orangefs: Convert to use the new mount APIEric Sandeen
Convert the orangefs filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.

2019-05-03orangefs: add orangefs_revalidate_mappingMartin Brandenburg
This is modeled after NFS, except our method is different. We use a simple timer to determine whether to invalidate the page cache. This is bound to perform. This addes a sysfs parameter cache_timeout_msecs which controls the time between page cache invalidations.

2016-11-07orangefs: clean up debugfsMike Marshall
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.

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>

2016-02-19orangefs: delay freeing slot until cancel completesAl Viro
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 Marshall
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 Viro
* 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>
