[1. ] One line summary of the problem:
Updated check.c to fix `devfs_handle' undeclared error and
mtdblock_ro.c,
[2. ] Full description of the problem/report:
Compiling under Linux 2.4.19 resulted in errors which appear to be bugs
which I fixed:

FIX: Defined "io_request_lock" in mtdblock_request function.
Elsewhere in code, there were function calls with "not enough

and I added the missing argument (3 expected vs 2 given).

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
[X.] Other notes, patches, fixes, workarounds:
None - see sections 6, 7 above.
Well. Ok. My workaround was to drop it after fixing 5 bugs associated
with the
above report. I just downloaded linux-2.4.19.tar.gz and will rebuild
from this
one (even though I have 2.4.19 already, but I don't trust my source now
and I
need SCSI emulation to get the CD-RW applications running on my
system).
Thanks & Regards,
Art
