[PATCH v6 0/9] Allow changing bs->file on reopen

Posted by Vladimir Sementsov-Ogievskiy 1 week, 4 days ago
Note that this is only "subject" part of original Alberto's
"[PATCH v4 0/6] Allow changing bs->file on reopen" which also included
multiple reopen and dropping x- prefix of reopen together with some
refactoring.

v6: rebased
08: changed error message in test
09: somehow, now '.' are spread in test output

Now, v6 based on two first simple patches of
  "[PATCH v5 00/35] block: publish backup-top filter"
Based-on: <20210610112618.127378-1-vsementsov@virtuozzo.com>

So, if this goes first, just take first two patches of
"[PATCH v5 00/35] block: publish backup-top filter" which are already
reviewed by Max.

v5:
1-7: new
8: changed a lot
9: unchanged

Alberto Garcia (2):
  block: Allow changing bs->file on reopen
  iotests: Test replacing files with x-blockdev-reopen

Vladimir Sementsov-Ogievskiy (7):
  block: introduce bdrv_remove_file_or_backing_child()
  block: introduce bdrv_set_file_or_backing_noperm()
  block: bdrv_reopen_parse_backing(): don't check aio context
  block: bdrv_reopen_parse_backing(): don't check frozen child
  block: bdrv_reopen_parse_backing(): simplify handling implicit filters
  block: move supports_backing check to
    bdrv_set_file_or_backing_noperm()
  block: BDRVReopenState: drop replace_backing_bs field
