47  * Support for robust futexes: the kernel cleans up held futexes at
52  * Per-lock list entry - embedded in user-space locks, somewhere close
53  * to the futex field. (Note: user-space uses a double-linked list to
65  * Per-thread list head:
79 	 * This relative offset is set by user-space, it gives the kernel
81 	 * we keep userspace flexible, to freely shape its data-structure,
88 	 * up a lock's links. So to handle this race, userspace first
89 	 * sets this field to the address of the to-be-taken lock,
107  * a FUTEX_WAKE on such futexes, after setting the bit, to wake
108  * up any possible waiters:
113  * The rest of the robust-futex field is for the TID:
