The linux-2.4.9-ac10-rmk2-np1 had its drivers/mtd, fs/jffs2, and
include/linux/mtd directories deleted, and replaced with those from CVS.
Finally, include/linux/jffs2*.h were copied over. Is there something that
I could have mis-merged?
Is there an obvious way to troubleshoot the mount process? I have
a trace of the mount after giving a "echo 9 >/proc/sys/kernel/printk"
but it's kinda long. Each block is correctly summarized, here are
the first two:
Block at 0x00000000: free 0x0000e540, dirty 0x00000000, used 0x00001ac0
Block at 0x00010000: free 0x0000fff4, dirty 0x00000000, used 0x0000000c
and of course 0x00020000 through 0x000f0000 are just like 0x00010000.
Oddly, that last run did _not_ give the "No clean _or_ dirty blocks to
GC from!" message. printk levels 6 and 7 reproducibly give it, but
levels 8 and 9 do not. printk levels 5 and lower are silent. Is there
a thread synchronization issue, maybe?
