Looks good, but why no --branch anymore? :) (I can also try adding it back on top). Paolo > Signed-off-by: Daniel P.

It felt redundant to me. I guess it could be used to force interpretation of the arg as a git revlist, even if it lacks '..' ? Regards, Daniel

Currently before submitting a series, devs should run checkpatch.pl across each patch to be submitted. This can be automated using a command such as: git rebase -i master -x 'git show | ./scripts/checkpatch.pl -' This is rather long winded to type, so this patch introduces a way to tell checkpatch.pl to validate a series of GIT revisions. If checkpatch.pl is given a single argument that contains a literal '..', this is interpreted as a GIT revision list. For example: $ ./scripts/checkpatch.pl master.. total: 0 errors, 0 warnings, 297 lines checked b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission. total: 0 errors, 0 warnings, 182 lines checked 2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission. total: 0 errors, 0 warnings, 102 lines checked 11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission. If a genuine patch filename contains the characters '..' it is possible to force interpretation of the arg as a patch $ ./scripts/checkpatch.pl --patch master.. will force it to load a patch file called "master.."
