Date: Wed, 10 Jun 2020 21:23:01 +0300 [thread overview]
Message-ID: <20200610182305.3462-1-vsementsov@virtuozzo.com> (raw)
Recent changes in NBD protocol allowed to use some commands without
max_block restriction. Let's drop the restrictions.
NBD change is here:

v3: first two patches from v2 was merged. Let's continue with the rest.

block: add max_pwrite_zeroes_fast to BlockLimits
block/nbd: define new max_write_zero_fast limit
block/io: refactor bdrv_co_do_pwrite_zeroes head calculation
block/io: auto-no-fallback for write-zeroes
