Sigh. Another MTD deadlock, and cause of scheduling badness on UP preempt.
David, I think MTD needs an audit to ensure that no further cases exist.
static void cfi_intelext_sync (struct mtd_info *mtd)
{
for (i=0; !ret && i<cfi->numchips; i++) {
chip = &cfi->chips[i];
spin_lock(chip->mutex);
ret = get_chip(map, chip, chip->start, FL_SYNCING);
...
}
/* Unlock the chips again */
for (i--; i >=0; i--) {
chip = &cfi->chips[i];
spin_lock(chip->mutex);
...
spin_unlock(chip->mutex);
}
}
