Ext3 users - Feb 2001 - ext3-0.0.6a available

Hi,

ext3-0.0.6a has been uploaded to

	ftp.uk.linux.org:/pub/linux/sct/fs/jfs/ext3-0.0.6a.tar.gz

and

	ftp.*.kernel.org:/pub/linux/kernel/people/sct/ext3/ext3-0.0.6a.tar.gz

This version changes the way dirty buffers are marked to protect
against device drivers which might block in the ll_rw_block()
function.  (Loop and lvm are examples.)  It should also fix a rare but
persistent report of "buffer already locked" failures.

Other, more minor fixes include fixing the typo which reversed the
behaviour of ordered and writeback data modes in 0.0.5e, and a couple
of fixes for truncates to make sure that they commit to disk
atomically even when being split over multiple transactions.

Please use the e2fsprogs-WIP-0117 release for e2fsck with this ext3
release, available from

	ftp://download.sourceforge.net/pub/sourceforge

Cheers,
 Stephen.

Changes in this release
-----------------------

0.0.6a:

Fix typo: ordered and writeback data modes were working the wrong way
around.

Rework the dirty buffer handling: dirty flags are now held in a
private
flag while buffers are journaled, so the block device mid-layers see
those buffers as clean and non-flushable.

Fix some truncate recovery problems: not all filesystem state was
being
flushed in large truncates when we had to split the truncate over
multiple transactions, so the on-disk inode might be slightly
inconsistent after a crash.

Clear the dirty bits when forgetting buffers (prevents aborted
truncates
from leaving behind zeroed-out indirect buffers).

I hate to sound impatient (but I am :-) but will 0.0.6b be uploaded
soonish?

I think there is a typo in the ext3 patch in this kit.  In the file
ext3-0.0.6a/ext3-0.0.5e_to_0.0.6a.diff at line 458 there is a hunk of
patch which reads:

@@ -871,9 +885,12 @@

        if(buf->b_dev == B_FREE) {
                printk("Attempt to refile free buffer\n");
++              *((char *) 0) = 0;
                return;
        }

This is patching fs/buffer.c.

Should there actually be two `+' at the beginning of that line?  Is
this a "patch" syntax or some other syntax that I am not aware of?
