| H A D | 245 | diff ecd30d2d978493f2280798f4c48f674d6290efa4 Thu Jun 10 07:05:36 CDT 2021 Alberto Garcia <berto@igalia.com> block: Allow changing bs->file on reopen
When the x-blockdev-reopen was added it allowed reconfiguring the
graph by replacing backing files, but changing the 'file' option was
forbidden. Because of this restriction some operations are not
possible, notably inserting and removing block filters.
This patch adds support for replacing the 'file' option. This is
similar to replacing the backing file and the user is likewise
responsible for the correctness of the resulting graph, otherwise this
can lead to data corruption.
