| |
According to rtsx_chip.c and xd.c, the driver may sleep under a spin lock. The function call path is: rtsx_exclusive_enter_ss (acquire the lock by spin_lock) rtsx_enter_ss rtsx_power_off_card xd_cleanup_work xd_delay_write xd_finish_write xd_set_unused_block xd_build_l2p_tbl vmalloc --> may sleep
This bug is found by my static analysis tool and my code review. I hope to fix it, but I do not have a good solution.
Thanks, Jia-Ju Bai
