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
