2015-07-01fuse: req state use flagsMiklos Szeredi
Use flags for representing the state in fuse_req. This is needed since req->list will be protected by different locks in different states, hence we'll want the state itself to be split into distinct bits, each protected with the relevant lock in that state. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2015-07-01fuse: simplify req statesMiklos Szeredi
FUSE_REQ_INIT is actually the same state as FUSE_REQ_PENDING and FUSE_REQ_READING and FUSE_REQ_WRITING can be merged into a common FUSE_REQ_IO state. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Reviewed-by: Ashish Samant <ashish.samant@oracle.com>
2015-07-01fuse: don't hold lock over request_wait_answer()Miklos Szeredi
Only hold fc->lock over sections of request_wait_answer() that actually need it. If wait_event_interruptible() returns zero, it means that the request finished. Need to add memory barriers, though, to make sure that all relevant data in the request is synchronized. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2015-07-01fuse: simplify unique ctrMiklos Szeredi
Since it's a 64bit counter, it's never gonna wrap around. Remove code dealing with that possibility. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Reviewed-by: Ashish Samant <ashish.samant@oracle.com>
2015-07-01fuse: rework abortMiklos Szeredi
Splice fc->pending and fc->processing lists into a common kill list while holding fc->lock. By the time we release fc->lock, pending and processing lists are empty and the io list contains only locked requests.

Reuse req->waitq.lock for protecting FR_ABORTED and FR_LOCKED flags. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Reviewed-by: Ashish Samant <ashish.samant@oracle.com>
2015-07-01fuse: req use bitopsMiklos Szeredi
Finer grained locking will mean there's no single lock to protect modification of bitfileds in fuse_req. So move to using bitops. Can use the non-atomic variants for those which happen while the request definitely has only one reference.

2015-07-01fuse: call fuse_abort_conn() in dev releaseMiklos Szeredi
fuse_abort_conn() does all the work done by fuse_dev_release() and more. "More" consists of: end_io_requests(fc); wake_up_all(&fc->waitq); kill_fasync(&fc->fasync, SIGIO, POLL_IN); All of which should be no-op (WARN_ON's added).

2015-07-01fuse: check conn_error earlierMiklos Szeredi
fc->conn_error is set once in FUSE_INIT reply and never cleared. Check it in request allocation, there's no sense in doing all the preparation if sending will surely fail. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Reviewed-by: Ashish Samant <ashish.samant@oracle.com>
2015-07-01fuse: account as waiting before queuing for backgroundMiklos Szeredi
Move accounting of fc->num_waiting to the point where the request actually starts waiting. This is earlier than the current queue_request() for background requests, since they might be waiting on the fc->bg_queue before being queued on fc->pending.

2015-07-01fuse: reset waitingMiklos Szeredi

2015-07-01fuse: fix background request if not connectedMiklos Szeredi
request_end() expects fc->num_background and fc->active_background to have been incremented, which is not the case in fuse_request_send_nowait() failure path. So instead just call the ->end() callback (which is actually set by all callers). Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Reviewed-by: Ashish Samant <ashish.samant@oracle.com>
2015-07-01fuse: initialize fc->release before calling itMiklos Szeredi

2015-06-30genalloc: rename of_get_named_gen_pool() to of_gen_pool_get()Vladimir Zapolskiy
To be consistent with other kernel interface namings, rename of_get_named_gen_pool() to of_gen_pool_get(). In the original function name "_named" suffix references to a device tree property, which contains a phandle to a device and the corresponding device driver is assumed to register a gen_pool object. Due to a weak relation and to avoid any confusion (e.g. in future possible scenario if gen_pool objects are named) the suffix is removed.

2015-06-30drivers/scsi/scsi_debug.c: resolve sg buffer const-ness issueDave Gordon
do_device_access() takes a separate parameter to indicate the direction of data transfer, which it used to use to select the appropriate function out of sg_pcopy_{to,from}_buffer(). However these two functions now have So this patch makes it bypass these wrappers and call the underlying function sg_copy_buffer() directly; this has the same calling style as do_device_access() i.e. a separate direction-of-transfer parameter and no pointers-to-const, so skipping the wrappers not only eliminates the warning, it also make the code simpler :) [akpm@linux-foundation.org: fix very broken build] Signed-off-by: Dave Gordon <david.s.gordon@intel.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2015-06-30lib/scatterlist: mark input buffer parameters as 'const'Dave Gordon
The 'buf' parameter of sg(p)copy_from_buffer() can and should be const-qualified, although because of the shared implementation of _to_buffer() and _from_buffer(), we have to cast this away internally. This means that callers who have a 'const' buffer containing the data to be copied to the sg-list no longer have to cast away the const-ness themselves. It also enables improved coverage by code analysis tools. Signed-off-by: Dave Gordon <david.s.gordon@intel.com> Cc: Akinobu Mita <akinobu.mita@gmail.com> Cc: "Martin K.

2015-06-30lib/scatterlist.c: fix kerneldoc for sg_pcopy_{to,from}_buffer()Dave Gordon
The kerneldoc for the functions doesn't match the code; the last two parameters (buflen, skip) have been transposed, which is confusing, especially as they're both integral types and the compiler won't warn about swapping them. These functions and the kerneldoc were introduced in commit: df642cea lib/scatterlist: introduce sg_pcopy_from_buffer() ... Author: Akinobu Mita <akinobu.mita@gmail.com> Date: Mon Jul 8 16:01:54 2013 -0700 The only difference between sg_pcopy_{from,to}_buffer() and sg_copy_{from,to}_buffer() is an additional argument that specifies the number of bytes to skip the SG list before copying. The functions have the extra argument at the end, but the kerneldoc lists it in penultimate position.
