Subject: [PATCH v2 0/9] drop unallocated_blocks_are_zero
Date: Thu, 7 May 2020 11:47:51 +0300 [thread overview]
Message-ID: <20200507084800.20596-1-vsementsov@virtuozzo.com> (raw)
Hi all!
v2 (by Eric's review):
01: moved to the start of the series, add Eric's r-b
02: new
03-04: improve commit message
05: add Eric's r-b
06-08: improve commit message a bit, add Eric's r-b
09: typos and wording, rebase on 02
This is first step to block-status refactoring, and solves most simple
problem mentioned in my investigation of block-status described in
the thread "backing chain & block status & filters":
https://lists.gnu.org/archive/html/qemu-devel/2020-04/msg04706.html
unallocated_blocks_are_zero doesn't simplify all the logic about
block-status, and happily it's not needed, as shown by the following
patches. So, let's get rid of it.
Vladimir Sementsov-Ogievskiy (9):
qemu-img: convert: don't use unallocated_blocks_are_zero
block: inline bdrv_unallocated_blocks_are_zero()
block/vdi: return ZERO block-status when appropriate
block/vpc: return ZERO block-status when appropriate
block/crypto: drop unallocated_blocks_are_zero
block/iscsi: drop unallocated_blocks_are_zero
block/file-posix: drop unallocated_blocks_are_zero
block/vhdx: drop unallocated_blocks_are_zero
block: drop unallocated_blocks_are_zero
