When Not list_empty - tests whether a list is empty*@head: the list to test. cycle

1171

req = list_first_entry - get the first element from a list*@ptr: the list head to take the element from.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.* Note, that list is expected to be not empty.(done, structio_kiocb, list)

1172

deletes entry from list

1174

io_cqring_fill_event(req, result)

1175

1177

If _dec_and_test - decrement a refcount and test if it is 0*@r: the refcount* Similar to atomic_dec_and_test(), it will WARN on underflow and fail to* decrement when saturated at REFCOUNT_SATURATED Then

1183

If (flags & (ctx owns file | linked sqes )) == ctx owns file && Not io_is_fallback_req(req) && Not io Then

1186

reqs[to_free++] = req

1187

If to_free == ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(reqs) Then io_free_req_many(ctx, reqs, & to_free)

Else
