Hi all, I've found some strange ext3 ioctl under CONFIG_JBD_DEBUG: EXT3_IOC_WAIT_FOR_READONLY. I had DEBUG_SPINLOCK enabled and my kernel was crashed on wait-for-readonly.c test from ext3-tools because ioctl handler tries to use uninitialized EXT3_SB(sb)->ro_wait_queue and waits EXT3_SB(sb)->turn_ro_timer that nobody uses in kernel. I do not understand the function of this ioctl and believe this code is dead long time ago. From my POV it makes sense to remove it from kernel instead of fixing it. Has somebody any objections?
