2022-01-12leds: lp55xx: initialise output direction from dtsMerlijn Wajer
Commit a5d3d1adc95f ("leds: lp55xx: Initialize enable GPIO direction to output") attempts to fix this, but the fix did not work since at least for the Nokia N900 the value needs to be set to HIGH, per the device tree. So rather than hardcoding the value to a potentially invalid value for some devices, let's set direction in lp55xx_init_device. Fixes: a5d3d1adc95f ("leds: lp55xx: Initialize enable GPIO direction to output") Fixes: 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx") Fixes: ac219bf3c9bd ("leds: lp55xx: Convert to use GPIO descriptors") Signed-off-by: Merlijn Wajer <merlijn@wizzup.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Pavel Machek <pavel@ucw.cz>

2022-01-12xfs: fix online fsck handling of v5 feature bits on secondary supersDarrick J. Wong
While I was auditing the code in xfs_repair that adds feature bits to existing V5 filesystems, I decided to have a look at how online fsck handles feature bits, and I found a few problems: 1) ATTR2 is added to the primary super when an xattr is set to a file, but that isn't consistently propagated to secondary supers. This isn't a corruption, merely a discrepancy that repair will fix if it ever has to restore the primary from a secondary. Hence, if we find a mismatch on a secondary, this is a preen condition, not a corruption. 2) There are more compat and ro_compat features now than there used to be, but we mask off the newer features from testing. This means we ignore inconsistencies in the INOBTCOUNT and BIGTIME features, which is wrong. Get rid of the masking and compare directly. 3) NEEDSREPAIR, when set on a secondary, is ignored by everyone. Hence a mismatch here should also be flagged for preening, and online repair should clear the flag. Right now we ignore it due to (2). 4) log_incompat features are ephemeral, since we can clear the feature bit as soon as the log no longer contains live records for a particular log feature. As such, the only copy we care about is the one in the primary super. If we find any bits set in the secondary super, we should flag that for preening, and clear the bits if the user elects to repair it. Signed-off-by: Darrick J.

2022-01-12perf bpf: Rename 'cpu' to 'cpu_map_idx'Ian Rogers
Synchronize the caller in evsel with the called function. Shorten 3 lines of code in bperf_read by using perf_cpu_map__for_each_cpu(). This code is frequently using variables named cpu as cpu map indices, which doesn't matter as all CPUs are in the CPU map. It is strange in some cases the cpumap is used at all. Committer notes: Found when building with BUILD_BPF_SKEL=1: Remove unused 'num_cpu' variable in bperf__read().

2022-01-12libperf: Switch cpu to more accurate cpu_map_idxIan Rogers
Modify variable names and adopt perf_cpu_map__for_each_cpu() in perf_evsel__open(). Renaming is done by looking for consistency in API usage.

2022-01-12perf evsel: Derive CPUs and threads in alloc_countsIan Rogers
Passing the number of CPUs and threads allows for an evsel's counts to be mismatched to its cpu map. To avoid this always derive the counts size from the cpu map. Change openat-syscall-all-cpus to set the cpus to allow for this to work.
