    0704c57 can: m_can_platform: remove unnecessary m_can_class_resume() call

removed the m_can_class_resume() call in the runtime resume path to get
rid of a infinite recursion, so the runtime resume now only handles the device
clocks.

Unfortunately it did not remove the complementary m_can_class_suspend() call in
the runtime suspend function, so those paths are now unbalanced, which causes
the pinctrl state to get stuck on the "sleep" state, which breaks all CAN
functionality on SoCs where this state is defined. Remove the
m_can_class_suspend() call to fix this.

btrfs: fix resolving backrefs for inline extent followed by prealloc
560840a 
If a file consists of an inline extent followed by a regular or prealloc
extent, then a legitimate attempt to resolve a logical address in the
non-inline region will result in add_all_parents reading the invalid
offset field of the inline extent. If the inline extent item is placed
in the leaf eb s.t. it is the first item, attempting to access the
offset field will not only be meaningless, it will go past the end of
the eb and cause this panic:

selftests/bpf: Relax time_tai test for equal timestamps in tai_forward
dd40311 
We're observing test flakiness on an arm64 platform which might not
have timestamps as precise as x86. The test log looks like:

  test_time_tai:PASS:tai_open 0 nsec
  test_time_tai:PASS:test_run 0 nsec
  test_time_tai:PASS:tai_ts1 0 nsec
  test_time_tai:PASS:tai_ts2 0 nsec
  test_time_tai:FAIL:tai_forward unexpected tai_forward: actual 1702348135471494160 <= expected 1702348135471494160
  test_time_tai:PASS:tai_gettime 0 nsec
  test_time_tai:PASS:tai_future_ts1 0 nsec
  test_time_tai:PASS:tai_future_ts2 0 nsec
  test_time_tai:PASS:tai_range_ts1 0 nsec
  test_time_tai:PASS:tai_range_ts2 0 nsec
  #199     time_tai:FAIL

This patch changes ASSERT_GT to ASSERT_GE in the tai_forward assertion
so that equal timestamps are permitted.
