Basically I run checkpatch.py each time. :) >=20 > # ./scripts/checkpatch.pl 0001-crypto-add-virtio-crypto-driver.patch=20 > total: 0 errors, 0 warnings, 1873 lines checked >=20 > 0001-crypto-add-virtio-crypto-driver.patch has no obvious style problems = and is ready for submission. Looks like a bug in checkpatch.pl: # check for spinlock_t definitions without a comment. if ($line =3D~ /^.\s*(struct\s+mutex|spinlock_t)\s+\S+;/ || $line =3D~ /^.\s*(DEFINE_MUTEX)\s*\(/) { my $which =3D $1; if (!ctx_has_comment($first_line, $linenr)) { CHK("UNCOMMENTED_DEFINITION", "$1 definition without comment\n" . $herecurr); } } Since your mutex definition has the 'static' keyword in front of it checkpatch.pl misses it! Andy: Is this checkpatch.pl behavior intentional?
