Subject: [patch 22/27] ext3 truncate fix
Date: Thu, 04 Jul 2002 16:55:08 -0700	[thread overview]
Message-ID: <3D24E05C.4D57A492@zip.com.au> (raw)



Forward-port of a fix which Stephen has applied to ext3's 2.4 CVS tree.

Fix for a rare problem seen under stress in data=journal mode: if we
have to restart a truncate transaction while traversing the inode's
direct blocks, we need to deal with bh==NULL in ext3_clear_blocks.
