Not as big as 4.9 was, but still just over a thousand changes. We almost broke even of lines added vs. removed, as the slicoss driver was removed (got a "clean" driver for the same hardware through the netdev tree), and some iio drivers were also dropped, but I think we ended up adding a few thousand lines to the source tree in the end. Other than that it's a lot of minor fixes all over the place, nothing major stands out at all. All of these have been in linux-next for a while. There will be a merge conflict with Al's vfs tree in the lustre code, but the resolution for that should be pretty simple, that too has been in linux-next" * tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1002 commits) staging: comedi: comedidev.h: Document usage of 'detach' handler staging: fsl-mc: remove unnecessary info prints from bus driver staging: fsl-mc: add sysfs ABI doc staging/lustre/o2iblnd: Fix misspelled attemps->attempts staging/lustre/o2iblnd: Fix misspelling intialized->intialized staging/lustre: Convert all bare unsigned to unsigned int staging/lustre/socklnd: Fix whitespace problem staging/lustre/o2iblnd: Add missing space staging/lustre/lnetselftest: Fix potential integer overflow staging: greybus: audio_module: remove redundant OOM message staging: dgnc: Fix lines longer than 80 characters staging: dgnc: fix blank line after '{' warnings. staging/android: remove Sync Framework tasks from TODO staging/lustre/osc: Revert erroneous list_for_each_entry_safe use staging: slicoss: remove the staging driver staging: lustre: libcfs: remove lnet upcall code staging: lustre: remove set but unused variables staging: lustre: osc: set lock data for readahead lock staging: lustre: import: don't reconnect during connect interpret staging: lustre: clio: remove mtime check in vvp_io_fault_start() ...
| * staging: comedi: comedidev.h: Document usage of 'detach' handlerIan Abbott2016-12-081-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Document when the "detach" handler function pointed to by the `detach` member of a `struct comedi_driver` is called by the comedi core, and how the "attach" and "auto_attach" handlers can defer clean-up to it when they return an error to the comedi core. This is already mentioned as part of the documentation for `comedi_auto_config()`, but is useful to document it for `struct comedi_driver` as well, since `comedi_auto_config()` is not usually called directly by low-level comedi drivers, and it is not called at all for "legacy" comedi devices that are configured manually.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have been having a lot of unexplainable crashes in osc_lru_shrink lately that I could not see a good explanation for and then I found this patch that slip under the radar somehow that incorrectly converted while loop for lru list iteration into list_for_each_entry_safe totally ignoring that in the body of the loop we drop spinlocks guarding this list and move list entries around. Not sure why it was not showing up right away, perhaps some of the more recent LRU changes committed caused some extra pressure on this code that finally highlighted the breakage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In fault IO initialization, inode's mtime is saved, and after getting locks, when the IO is about to start, vvp_io_fault_start() checks the mtime's intactness. It's a false alarm, since the timestamp from MDS could be stale, we maintain mtime mainly on OST objects, and if the check in vvp_io_fault_start() happens before mtime on OST objects are merged, it will get wrong timestamp from the inode, even the timestamp it fetched in vvp_io_fault_init() could be wrong in the first place. This patch remove the mtime check in vvp_io_fault_start().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag should be cleared atomically after the op_data flag MDS_DATA_MODIFIED is packed. Otherwise, if there exists an operation to dirty the file again, the state may be missed on the MDT. Stop using spin lock lli_lock to protect operations of changing file flags; using bit operations instead.
