[GEDI] [PATCH v2 14/17] block: use int64_t instead of uint64_t in driver write handlers
Vladimir Sementsov-Ogievskiy
vsementsov at virtuozzo.com
Mon Apr 27 08:23:22 UTC 2020
We are generally moving to int64_t for both offset and bytes parameters
on all io paths. Convert driver write handlers parameters which are
already 64bit to signed type.
