Subject: [PATCH 0/4] ext4: Check journal inode extents more carefully
Date: Wed, 15 Jul 2020 15:18:08 +0200 [thread overview]
Message-ID: <20200715131812.7243-1-jack@suse.cz> (raw)
Hello!
This series changes ext4 to properly check extent tree blocks of journal inode.
Omitting these (which is a limitation of block validity checks) leads to crash
in ext4_cache_extents() in case the extent tree of the journal inode is
suitably corrupted.
