Good job guys!!
2.2.3-pre1 fixes the CONFIG_FILTER option which allows DHCP to work.
I had reported the mke2fs on an 3x8G RAID array was running out of memory.
I'm using raid0145-19990128-2.2.0.gz
Andrea Arcangeli <[EMAIL PROTECTED]> posted a patch which I applied to
2.2.3-pre1 and I regenerated my RAID array with no problems at all. The
inode buffers looked like they got flushed out just fine -- no swapping
occurred, no out-of-memory conditions.
Here's the patch which allowed mke2fs on the RAID set:
