I've been using extents since the patch was introduced. I haven't seen
any corruption when using it with large files (ie. multimedia only). In
short, has there been any progress with getting fsck support? I'm 100%
in support of this patch going into mainline kernel as a non-default
option. It's perfect for partitions that deal with large files, but
still want ext3's fs corruption protection. I average 10700 blocks an
extent and see an extreme increase in performance over non-extents ext3
doing operations on files of the same size. I guess it's about time to
update.
