Revision 870f5681
ID | 870f5681c9dbafc738082b1fd48e0cc013bf43c7 |
block: after creating a live snapshot, make old image read-only
Currently, after a live snapshot of a drive, the image that has
been 'demoted' to be below the new active layer remains r/w.
This patch reopens it read-only.
Note that we do not check for error on the reopen(), because we
will not abort the snapshots if the reopen fails.
This patch depends on the bdrv_reopen() series.
