Well, I was getting a mount failure. There wasn't much info other than
that. If you look in the latest (20021202) jffs2 build.c file, you can
see if the kmalloc of c->blocks fails in jffs2_do_mount_fs, no debug
message is printed. Only a non-mem error is returned. That is
consistent with what I was seeing, even with the highest verbosity
debugging on.
I made the change to use vmalloc/vfree for c->blocks and that seemd to
fix the problem. kmalloc is indeed limited to 128KB. Of course, I
made the change to the 20020819 code. I'll try the vmalloc change with
the latest CVS code as well and see how that holds up.
