Subject: [PATCH 5/5] tests: add the r_meta_bg_shrink test
|
|
|
3b974a |
|
|
|
3b974a |
This test checks to make sure resize2fs can properly handle a file
|
|
|
3b974a |
system which started life as a normal ext4 file system and then was
|
|
|
3b974a |
grown to a size where meta_bg was enabled, and then shrunk back below
|
|
|
3b974a |
the point where the meta_bg format is still needed.
