David,
In a netshell, here is the test case:
Using 20050712 cvs mtd on an Atmel AT91RM9200 running linux-2.6.9
with a NAND part and doing:
1. Erase a jffs2 NAND partition, then mount it.
2. Make 5000 170 byte files named test0000.bin through test4999.bin in
the partition.
3. run "ls -Rl" on the partition mount point.
4. remove all files in the partition via "rm -rf"
A few seconds after the command line prompt appears the gc code goes
into a 12 minute temporary "hang" loop in jffs2_flush_wbuf_gc() in
wbuf.c starting at:
} else while (old_wbuf_len &&
old_wbuf_ofs == c->wbuf_ofs) {
