*
* These are flags that are so syscall-specific that a user passing these flags
* to the wrong syscall is so "clearly wrong" that we can safely call such
* usage "undefined behaviour".
*
* For example, the constants AT_REMOVEDIR and AT_EACCESS have the same value.
* AT_EACCESS is meaningful only to faccessat, while AT_REMOVEDIR is meaningful
* only to unlinkat. The two functions do completely different things and
* therefore, the flags can be allowed to overlap. For example, passing
* AT_REMOVEDIR to faccessat would be undefined behavior and thus treating it
* equivalent to AT_EACCESS is valid undefined behavior.
*

* reuse already existing flags first. This leaves us with as many unused bits

* almost out of 32-bit flags. :-)
*
* We have recently hoisted FS_IOC_FSGETXATTR / FS_IOC_FSSETXATTR from
* XFS to the generic FS level interface. This uses a structure that
* has padding and hence has more room to grow, so it may be more
* appropriate for many new use cases.

* @stack: Specify the location of the stack for the

* Note, @stack is expected to point to the
* lowest address. The stack direction will be
* determined by the kernel and set up
* appropriately based on @stack_size.
* @stack_size: The size of the stack for the child process.
* @tls: If CLONE_SETTLS is set, the tls descriptor
* is set to tls.
* @set_tid: Pointer to an array of type *pid_t. The size
* of the array is defined using @set_tid_size.
* This array is used to select PIDs/TIDs for

* this defines the PID in the most nested PID

* defines the PID in the parent PID namespace of

* a file descriptor for the cgroup.
