Proto:int wake_bit_function(struct wait_queue_entry *wq_entry, unsigned mode, int sync, void *arg)

Type:int

Parameter:

TypeParameterName
struct wait_queue_entry *wq_entry
unsignedmode
intsync
void *arg
23  key = arg
24  wait_bit = container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(wq_entry, structwait_bit_queue_entry, wq_entry)
26  If flags != flags || bit_nr != bit_nr || st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from Then Return 0
