nitpick: we like to do this commit quoting style:

  7f5f873c6a07 ("rculist: Use WRITE_ONCE() when deleting from reader-visible list")

Checkpatch catches that:

ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'Commit 7f5f873c6a07 ("rculist: Use WRITE_ONCE() when deleting from reader-visible list")'
#21: 
Commit 7f5f873c6a07 added the use of the WRITE_ONCE macro to the kernel
