Subject: [PATCH 013/217] test/libndctl: Use ndctl_region_set_ro() to change
|
|
disk read-only state
|
|
|
|
Kernel commit 52f019d43c22 ("block: add a hard-readonly flag to struct
|
|
gendisk") broke the read-only management test, by fixing the broken
|
|
behavior that BLKROSET could make a block device read-write even when the
|
|
disk is read-only. The fix [1] propagates changes of the region
|
|
read-only state to the underlying disk. Add ndctl_region_set_ro() ahead of
|
|
BLKROSET so that BLKROSET does not conflict the block_device state with the
|
|
disk state.
