SYNOPSIS

int wait_on_bit_lock_action(unsigned long * word, int bit, wait_bit_action_f * action, unsigned mode);

ARGUMENTS

word

the word being waited on, a kernel virtual address

bit

the bit of the word being waited on

action

the function used to sleep, which may take special actions

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 set it, and allow the waiting action to be specified. This is like wait_on_bit but allows fine control of how the waiting is done.

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.
