9fa248c65b fuse: fix readdir cache race
There's a race in fuse's readdir cache that can result in an uninitilized
page being read.  The page lock is supposed to prevent this from happening
but in the following case it doesn't:

Two fuse_add_dirent_to_cache() start out and get the same parameters
(size=0,offset=0).  One of them wins the race to create and lock the page,
after which it fills in data, sets rdc.size and unlocks the page.

In the meantime the page gets evicted from the cache before the other
instance gets to run.  That one also creates the page, but finds the
size to be mismatched, bails out and leaves the uninitialized page in the
cache.

Fix by marking a filled page uptodate and ignoring non-uptodate pages.

febdb8eea9 staging: r8188eu: remove bLedLinkBlinkInProgress
Remove the bLedLinkBlinkInProgress component from struct led_priv. Its
only use is to block requests for "link blinking" when this blinking
pattern is already active.

The "link blinking" pattern is a continuous blinking pattern (as opposed
to other patterns where we blink N times), it's no problem to restart this
pattern when it's already running.

b329f5ddc9 perf/x86/intel/lbr: Use setup_clear_cpu_cap() instead of clear_cpu_cap()
clear_cpu_cap(&boot_cpu_data) is very similar to setup_clear_cpu_cap()
except that the latter also sets a bit in 'cpu_caps_cleared' which
later clears the same cap in secondary cpus, which is likely what is
meant here.

de3ee3f634 selftests: Use optional USERCFLAGS and USERLDFLAGS
This change enables to extend CFLAGS and LDFLAGS from command line, e.g.
to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static

USERCFLAGS and USERLDFLAGS are documented in
Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst

This should be backported (down to 5.10) to improve previous kernel
versions testing as well.

c9adc3bd11 dt-bindings: Remove "status" from schema examples, again
There's no reason to have "status" properties in examples. "okay" is the
default, and "disabled" turns off some schema checks ('required'
specifically).

A meta-schema check for this is pending, so hopefully the last time to
fix these.

Fix the indentation in intel,phy-thunderbay-emmc while we're here.
