Subject: checkpatch: cache last camelcase hash as .checkpatch-camelcase.<commit>
X-Git-Tag: omap-for-v3.11/fixes-for-merge-window~17^2~219
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=351b2a1fe2d06f44b4c06d377744b2ac408b7407;p=pandora-kernel.git

checkpatch: cache last camelcase hash as .checkpatch-camelcase.<commit>

Add a file to cache the CamelCase variables found by <commit> to reduce
the time it takes to scan the include/ directory.

Filename is '.checkpatch-camelcase.<commit>' and it is created only only
if a .git directory exists.

<commit> is determined by the last non-merge commit id in the
include/ path.

Reduces checkpatch run time by ~12 cpu seconds on my little netbook.
