Recent changes in NBD protocol allowed to use some commands without
max_block restriction. Let's drop the restrictions.
NBD change is here:
https://github.com/NetworkBlockDevice/nbd/commit/9f30fedb8699f151e7ef4ccc07e624330be3316b#diff-762fb7c670348da69cc9050ef58fe3ae
v4: fix auto_no_fallback variable usage in 04:
- initialize it
- unset it on error
Hope, it will fix bug reported by patchew
Vladimir Sementsov-Ogievskiy (4):
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
