[PATCH v3 2/8] block: Add no_fallback parameter to bdrv_co_truncate() |
|
Date: |
Fri, 22 Nov 2019 17:05:05 +0100 |
This adds a no_fallback parameter to bdrv_co_truncate(), bdrv_truncate()
and blk_truncate() in preparation for a fix that potentially needs to
zero-write the new area. no_fallback will use BDRV_REQ_NO_FALLBACK for
this operation and lets the truncate fail if an efficient zero write
isn't possible.
Only qmp_block_resize() passes true for this parameter because it is a
blocking monitor command, so we don't want to add more potentially slow
I/O operations to it than we already have.
All other users will accept even a slow fallback to avoid failure.
