From: Michael Haggerty Date: Wed, 1 Oct 2014 10:28:30 +0000 (+0200) Subject: try_merge_strategy(): use a statically-allocated lock_file object X-Git-Tag: v2.2.0-rc0~53^2~12 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/daccee387a7f3e4ca332649d5311b032a71892e2 try_merge_strategy(): use a statically-allocated lock_file object Even the one lockfile object needn't be allocated each time the function is called. Instead, define one statically-allocated lock_file object and reuse it for every call.
