Subject: [PATCH v12 00/14] Apply COR-filter to the block-stream permanently
Date: Thu, 22 Oct 2020 21:13:29 +0300 [thread overview]
Message-ID: <1603390423-980205-1-git-send-email-andrey.shinkevich@virtuozzo.com> (raw)
The node insert/remove functions were added at the block generic layer.
COR-filter options structure was added to the QAPI.
The test case #310 was added to check the 'bottom' node limit for COR.
The 'supported_read_flags' member was added to the BDS structure
(with the flags check at the block generic layer for drivers).
v12:
02: New.
03: Only the temporary drop filter function left.
05: New (suggested by Max)
06: 'base' -> 'bottom' option.
07: Fixes based on the review of the v11.
08: New.
09: The comment ext was modified.
10: The read flags check at the block generic layer.
11: COR flag was added.
12: The condition was fixed.
13: The 'backing-file' parameter returned. No deprecation.
14: The COR-filter 'add' function replaced with the 'insert node' generic
function. Fixes based on the review of the v11.

block: modify the comment for BDRV_REQ_PREFETCH flag
block: include supported_read_flags into BDS structure
copy-on-read: add support for read flags to COR-filter
copy-on-read: skip non-guest reads if no copy needed
