[PATCH v15 00/13] Apply COR-filter to the block-stream permanently |

Hi all!
Here is a new version of cor-filter in block-stream series. Main change
is freezing the chain in cor-filter itself.
v15:
02: s/ = / = /
add Max's r-b
03: add Max's r-b
04: since: 6.0
indent comment
add Max's r-b
05: changed commit msg
wording
document the default
since: 6.0
use bdrv_find_node(), fix errp overwriting
freeze the chain
check bottom is not filter
ref bottom_bs
06: limit to qcow2 to not care
use qemu-img rebase -u -b ''
07: use assert instead of abort
add Max's r-b
08: add Max's r-b
09: changed commit msg (was "stream: skip filters when writing backing file
name to QCOW2 header")
keep mostly same logic for the case when backing-file is specified, don't
do bdrv_find_backing_image()
10: don't restrict backing-file for now
11: add Max's r-b
12: add Max's r-b
13: chain is now frozen in filter, so the logic changed around add/remove
fitlter
Andrey Shinkevich (10):
copy-on-read: support preadv/pwritev_part functions
block: add API function to insert a node
copy-on-read: add filter drop function
qapi: add filter-node-name to block-stream
qapi: copy-on-read filter: add 'bottom' option
iotests: add #310 to test bottom node in COR driver
block: include supported_read_flags into BDS structure
copy-on-read: skip non-guest reads if no copy needed
stream: rework backing-file changing
block: apply COR-filter to block-stream jobs
Vladimir Sementsov-Ogievskiy (3):
qapi: block-stream: add "bottom" argument
iotests: 30: prepare to COR filter insertion by stream job
block/stream: add s->target_bs
