linux(4): Rename linux_timer.h to linux_time.h

2023-02-14T14:46:33+00:00

To avoid confusing people, rename linux_timer.h to linux_time.h,
as linux_timer.c is the implementation of timer syscalls only,
while linux_time.c contains implementation of all stuff declared
in linux_time.h.

linux(4): Fix get_robust_list() syscall return value.

2022-11-08T21:17:17+00:00

The system call returns the head of the robust futex list. The list head is stored
in the location pointed to by the head argument. When copying data between address
spaces use proper head storage size as it depends on an emulated ABI.
