Subject: [PATCH 04/22] ext4: Fix credit estimate for final inode freeing
Date: Fri, 4 Oct 2019 00:05:50 +0200 [thread overview]
Message-ID: <20191003220613.10791-4-jack@suse.cz> (raw)
In-Reply-To: <20191003215523.7313-1-jack@suse.cz>
Estimate for the number of credits needed for final freeing of inode in
ext4_evict_inode() was to small. We may modify 4 blocks (inode & sb for
orphan deletion, bitmap & group descriptor for inode freeing) and not
just 3.
Fixes: e50e5129f384 ("ext4: xattr-in-inode support")
