When the recovery master is down, the owner of $RECOVERY calls dlm_do_local_recovery_cleanup() to prune any $RECOVERY entries for dead nodes. The lock is in the granted list and the refcount must be 2. We should put twice to remove this lock. Otherwise, it will lead to a memory leak. Signed-off-by:

Commit e9fd702a ("audit: convert audit watches to use fsnotify instead of inotify") broke handling of renames in audit. Audit code wants to update inode number of an inode corresponding to watched name in a directory. When something gets renamed into a directory to a watched name, inotify previously passed moved inode to audit code however new fsnotify code passes directory inode where the change happened. That confuses audit and it starts watching parent directory instead of a file in a directory. This can be observed for example by doing: cd /tmp touch foo bar auditctl -w /tmp/foo touch foo mv bar foo touch foo In audit log we see events like: type=CONFIG_CHANGE msg=audit(1423563584.155:90): auid=1000 ses=2 op="updated rules" path="/tmp/foo" key=(null) list=4 res=1 ... type=PATH msg=audit(1423563584.155:91): item=2 name="bar" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE type=PATH msg=audit(1423563584.155:91): item=3 name="foo" inode=1046842 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=DELETE type=PATH msg=audit(1423563584.155:91): item=4 name="foo" inode=1046884 dev=08:0 2 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=CREATE ... and that's it - we see event for the first touch after creating the audit rule, we see events for rename but we don't see any event for the last touch. However we start seeing events for unrelated stuff happening in /tmp. Fix the problem by passing moved inode as data in the FS_MOVED_FROM and FS_MOVED_TO events instead of the directory where the change happens. This doesn't introduce any new problems because noone besides audit_watch.c cares about the passed value: fs/notify/fanotify/fanotify.c cares only about FSNOTIFY_EVENT_PATH events. fs/notify/dnotify/dnotify.c doesn't care about passed 'data' value at all. fs/notify/inotify/inotify_fsnotify.c uses 'data' only for FSNOTIFY_EVENT_PATH. kernel/audit_tree.c doesn't care about passed 'data' at all. kernel/audit_watch.c expects moved inode as 'data'.

Currently FAN_ONDIR is always set on a mark's ignored mask when the event mask is extended without FAN_MARK_ONDIR being set. This may result in events for directories being ignored unexpectedly for call sequences like fanotify_mark(fd, FAN_MARK_ADD, FAN_OPEN | FAN_ONDIR , AT_FDCWD, "dir"); fanotify_mark(fd, FAN_MARK_ADD, FAN_CLOSE, AT_FDCWD, "dir"); Also FAN_MARK_ONDIR is only honored when adding events to a mark's mask, but not for event removal. Fix both issues by not setting FAN_ONDIR implicitly on the ignore mask any more. Instead treat FAN_ONDIR as any other event flag and require FAN_MARK_ONDIR to be set by the user for both event mask and ignore mask. Furthermore take FAN_MARK_ONDIR into account when set for event removal. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

In fanotify_mark_remove_from_mask() a mark is destroyed if only one of both bitmasks (mask or ignored_mask) of a mark is cleared. However the other mask may still be set and contain information that should not be lost. So only destroy a mark if both masks are cleared. Signed-off-by:

Pull regulator updates from Mark Brown: "This has not been a busy release for the regulator framework, though we do have the first parts of some ongoing work from Bjorn Andersson to allow us to support more complex modern systems with dynamic configuration of regulators in suspend and idle states. - Support for device-specific properties on regulator nodes when using simplified DT parsing in the core from Krzysztof Kozlowski. - Restructuring of the load tracking code, intended to support future improvements in this area for more complex system designs. - New drivers for Maxim MAX77843 and Mediatek MT6397. - Lots of smaller fixes and improvements" * tag 'regulator-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (29 commits) regulator: max77843: Add max77843 regulator driver regulator: Fix build breakage on !REGULATOR regulator: Build sysfs entries with static attribute groups regulator: qcom-rpm: Make it possible to specify supply regulator: core: Consolidate drms update handling regulator: qcom-rpm: signedness bug in probe() regulator: da9211: Add gpio control for enable/disable of buck regulator: qcom_rpm: Don't update vreg->uV/mV if rpm_reg_write fails regulator: lp872x: Remove **regulators from struct lp872x regulator: da9211: fix unmatched of_node regulator: Update documentation after renaming function argument regulator: axp20x: Migrate to regulator core's simplified DT parsing code regulator: axp20x: Fill regulators_node and of_match descriptor fields regulator: pfuze100-regulator: add pfuze3000 support regulator: max77686: Document gpio properties regulator: Allow parsing custom properties when using simplified DT parsing regulator: max77686: Add GPIO control regulator: Copy config passed during registration regulator: tps65023: Constify struct regmap_config and regulator_ops regulator: max8649: Constify struct regmap_config and regulator_ops ...

Pull spi updates from Mark Brown: "The major highlight this release is a refactoring of the core to allow us to run synchronous transfers in the context of the caller when there is no contention for the bus. This improves performance in the very common case by eliminating context switches and reducing the number of hardware setup and teardown operations we need to perform.

There was a bad typo in commit 43759d4f ("random: use an improved fast_mix() function") and I didn't notice because it "looked right", so I saw what I expected to see when I reviewed it. Only months later did I look and notice it's not the Threefish-inspired mix function that I had designed and optimized. Mea Culpa. Each input bit still has a chance to affect each output bit, and the fast pool is spilled *long* before it fills, so it's not a total disaster, but it's definitely not the intended great improvement. I'm still working on finding better rotation constants. These are good enough, but since it's unrolled twice, it's possible to get better mixing for free by using eight different constants rather than repeating the same four. Signed-off-by:
