[PATCH 04/24] revision.[ch]: split freeing of revs->commit into a function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move the existing code for invoking free_commit_list() and setting
revs->commits to NULL into a new release_revisions_commit_list()
function. This will be used as part of a general free()-ing mechanism
for "struct rev_info".
