* gfs2: Protect gl->gl_object by spin lockAndreas Gruenbacher2017-07-059-21/+35
| | | | | | | | Put all remaining accesses to gl->gl_object under the gl->gl_lockref.lock spinlock to prevent races. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Bob Peterson <rpeterso@redhat.com>
* gfs2: Get rid of flush_delayed_work in gfs2_evict_inodeAndreas Gruenbacher2017-07-055-12/+46
| | | | | | | | | | | | | | | | | | | | So far, gfs2_evict_inode clears gl->gl_object and then flushes the glock work queue to make sure that inode glops which dereference gl->gl_object have finished running before the inode is destroyed. However, flushing the work queue may do more work than needed, and in particular, it may call into DLM, which we want to avoid here. Use a bit lock (GIF_GLOP_PENDING) to synchronize between the inode glops and gfs2_evict_inode instead to get rid of the flushing. In addition, flush the work queues of existing glocks before reusing them for new inodes to get those glocks into a known state: the glock state engine currently doesn't handle glock re-appropriation correctly. (We may be able to fix the glock state engine instead later.) Based on a patch by Steven Whitehouse <swhiteho@redhat.com>.

There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. - ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes.

The wrapper serves no real benefit aside from affording a more generic function name than the x86-specific 'mcsafe'. However this would not be the first time that x86 terminology leaked into the global namespace. For lack of better name, just use memcpy_mcsafe() directly. This conversion also catches a place where we should have been using plain memcpy, acpi_nfit_blk_single_io().

Since then the device-dax mechanism has filled the role of dax-mapping static device ranges. Now that we are moving ->direct_access() from a block_device operation to a dax_inode operation we would need block devices to map and carry their own dax_inode reference. Unless / until we decide to revive dax mapping of raw block devices through the dax_inode scheme, there is no need to carry read_dax_sector(). Its removal in turn allows for the removal of bdev_direct_access() and should have been included in commit 223757016837 ("block_dev: remove DAX leftovers").

Once fs/dax.c has been converted to use dax_operations the old dm_blk_direct_access() will be removed. A new helper dm_dax_get_live_target() is introduced to separate some of the dm-specifics from the direct_access implementation. This enabling is only for the top-level dm representation to upper layers. Converting target direct_access implementations is deferred to a separate patch.
