Subject: [PATCH v3 15/17] block: use int64_t instead of uint64_t in copy_range driver handlers
Date: Thu, 30 Apr 2020 14:10:31 +0300	[thread overview]
Message-ID: <20200430111033.29980-16-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20200430111033.29980-1-vsementsov@virtuozzo.com>

We are generally moving to int64_t for both offset and bytes parameters
on all io paths.

Main motivation is realization of 64-bit write_zeroes operation for
fast zeroing large disk chunks, up to the whole disk.

We chose signed type, to be consistent with off_t (which is signed) and
with possibility for signed return type (where negative value means
error).

So, convert driver copy_range handlers parameters which are already
64bit to signed type.
