Previously, anyone who set flag 'argpages' only filled req->pages[] and set per-request page_offset. This patch re-works all cases where argpages=1 to fill req->page_descs[] properly. Having req->page_descs[] filled properly allows to re-work fuse_copy_pages() to copy page fragments described by req->page_descs[]. This will be useful for next patches optimizing direct_IO.

The ability to save page pointers along with lengths and offsets in fuse_req will be useful to cover several iovec-s with a single fuse_req. Per-request page_offset is removed because anybody who need it can use req->page_descs[0].offset instead.

fuse_do_ioctl() already calculates the number of pages it's going to use. It is stored in 'num_pages' variable. So the patch simply uses it for allocating fuse_req. Signed-off-by: Maxim Patlasov <mpatlasov@parallels.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>

The patch allocates as many page pointers in fuse_req as needed to cover interval [pos .. pos+len-1]. Inline helper fuse_wr_pages() is introduced to hide this cumbersome arithmetic. Signed-off-by: Maxim Patlasov <mpatlasov@parallels.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>

The patch uses 'nr_pages' argument of fuse_readpages() as heuristics for the number of page pointers to allocate. This can be improved further by taking in consideration fc->max_read and gaps between page indices, but it's not clear whether it's worthy or not.

The patch reworks fuse_retrieve() to allocate only so many page pointers as needed. The core part of the patch is the following calculation: num_pages = (num + offset + PAGE_SIZE - 1) >> PAGE_SHIFT; (thanks Miklos for formula). All other changes are mostly shuffling lines.

The patch categorizes all fuse_get_req() invocations into two categories: - fuse_get_req_nopages(fc) - when caller doesn't care about req->pages - fuse_get_req(fc, n) - when caller need n page pointers (n > 0) Adding fuse_get_req_nopages() helps to avoid numerous fuse_get_req(fc, 0) scattered over code. Now it's clear from the first glance when a caller need fuse_req with page pointers. The patch doesn't make any logic changes. In multi-page case, it silly allocates array of FUSE_MAX_PAGES_PER_REQ page pointers. This will be amended by future patches.

The patch removes inline array of FUSE_MAX_PAGES_PER_REQ page pointers from fuse_req. Instead of that, req->pages may now point either to small inline array or to an array allocated dynamically. This essentially means that all callers of fuse_request_alloc[_nofs] should pass the number of pages needed explicitly. The patch doesn't make any logic changes.

This patch implements readdirplus support in FUSE, similar to NFS. The payload returned in the readdirplus call contains 'fuse_entry_out' structure thereby providing all the necessary inputs for 'faking' a lookup() operation on the spot. If the dentry and inode already existed (for e.g. in a re-run of ls -l) then just the inode attributes timeout and dentry timeout are refreshed. With a simple client->network->server implementation of a FUSE based filesystem, the following performance observations were made: Test: Performing a filesystem crawl over 20,000 files with sh# time ls -lR /mnt Without readdirplus: Run 1: 18.1s Run 2: 16.0s Run 3: 16.2s With readdirplus: Run 1: 4.1s Run 2: 3.8s Run 3: 3.8s The performance improvement is significant as it avoided 20,000 upcalls calls (lookup). Cache consistency is no worse than what already is. Signed-off-by: Anand V. Avati <avati@redhat.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>

This patch (as1643b) fixes a build error in ehci-hcd when compiling for ARM with allmodconfig: drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition drivers/usb/host/ehci-mxc.c:280:31: warning: 'ehci_mxc_driver' defined but not used [-Wunused-variable] drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition The fix is to convert ehci-mxc over to the new "ehci-hcd is a library" scheme so that it can coexist peacefully with the ehci-platform driver. As part of the conversion the ehci_mxc_priv data structure, which was allocated dynamically, is now placed where it belongs: in the private area at the end of struct ehci_hcd.

The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a module parameter] introduced the polling jack detection code, but it also moved the call of snd_hda_jack_set_dirty_all() in the resume path after resume/init ops call. This caused a regression when the jack state has been changed during power-down (e.g. in the power save mode). Since the driver doesn't probe the new jack state but keeps using the cached value due to no dirty flag, the pin state remains also as if the jack is still plugged. The fix is simply moving snd_hda_jack_set_dirty_all() to the original position. Reported-by: Manolo Díaz <diaz.manolo@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

This reverts commit eccf2979. The reason is that it broke TI WiLink shared transport on Panda. Also, callback functions should not be added to board files anymore, so revert to implementing the power functions in the driver itself. Additionally, changed a variable name ('status' to 'err') so that this revert compiles properly.

Commit 083b804c ("async: use workqueue for worker pool") made it possible that async jobs are moved from pending to running out-of-order. While pending async jobs will be queued and dispatched for execution in the same order, nothing guarantees they'll enter "1) move self to the running queue" of async_run_entry_fn() in the same order. Before the conversion, async implemented its own worker pool. An async worker, upon being woken up, fetches the first item from the pending list, which kept the executing lists sorted. The conversion to workqueue was done by adding work_struct to each async_entry and async just schedules the work item. The queueing and dispatching of such work items are still in order but now each worker thread is associated with a specific async_entry and moves that specific async_entry to the executing list. So, depending on which worker reaches that point earlier, which is non-deterministic, we may end up moving an async_entry with larger cookie before one with smaller one. This broke __lowest_in_progress(). running->domain may not be properly sorted and is not guaranteed to contain lower cookies than pending list when not empty. Fix it by ensuring sort-inserting to the running list and always looking at both pending and running when trying to determine the lowest cookie. Over time, the async synchronization implementation became quite messy. We better restructure it such that each async_entry is linked to two lists - one global and one per domain - and not move it when execution starts. There's no reason to distinguish pending and running. They behave the same for synchronization purposes.

The function tracer requires to update modules before they run, and uses the module notifier to do so. But if something else in the module notifiers registers a kprobe at one of these locations, before ftrace can get to it, then the system could fail.

Oleg Nesterov authored
putreg() assumes that the tracee is not running and pt_regs_access() can safely play with its stack. However a killed tracee can return from ptrace_stop() to the low-level asm code and do RESTORE_REST, this means that debugger can actually read/modify the kernel stack until the tracee does SAVE_REST again. set_task_blockstep() can race with SIGKILL too and in some sense this race is even worse, the very fact the tracee can be woken up breaks the logic. As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace() call, this ensures that nobody can ever wakeup the tracee while the debugger looks at it. Not only this fixes the mentioned problems, we can do some cleanups/simplifications in arch_ptrace() paths. Probably ptrace_unfreeze_traced() needs more callers, for example it makes sense to make the tracee killable for oom-killer before access_process_vm(). While at it, add the comment into may_ptrace_stop() to explain why ptrace_stop() still can't rely on SIGKILL and signal_pending_state().
