Subject: [PATCH] libparted: fix a bug in the nilfs2 probe function
|
|
|
|
* libparted/fs/nilfs2/nilfs2.c (nilfs2_probe): Reject this partition
|
|
if we get a negative sb2 offset. Passing a negative offset to
|
|
ped_geometry_read_alloc would evoke a failed assertion.
|
|
Bug introduced by 2010-07-09 commit d463e7de.
|
|
* NEWS: (Bug fixes): Mention it.
