SYNOPSIS

int wait_on_bit_lock_io(unsigned long * word, int bit, unsigned mode);

ARGUMENTS

word

the word being waited on, a kernel virtual address

bit

the bit of the word being waited on

mode

the task state to sleep in

DESCRIPTION

Use the standard hashed waitqueue table to wait for a bit to be cleared and then to atomically set it. This is similar to wait_on_bit, but calls io_schedule instead of schedule for the actual waiting.

Returns zero if the bit was (eventually) found to be clear and was set. Returns non-zero if a signal was delivered to the process and the mode allows that signal to wake the process.
