[PATCH v3 1/3] fast-import: rename mem_pool type to mp_block

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

 



This is part of a patch series to extract the memory pool logic in
fast-import into a more generalized version. The existing mem_pool type
maps more closely to a "block of memory" (mp_block) in the more
generalized memory pool. This commit renames the mem_pool to mp_block to
reduce churn in future patches.
