SYNOPSIS
- int wait_on_bit_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. This is similar to wait_on_bit, but calls io_schedule instead of schedule for the actual waiting.
Returned value will be zero if the bit was cleared, or non-zero if the process received a signal and the mode permitted wakeup on that signal.
