--- Comment #6 from Daniel Wagner <w...@monom.org> ---
I am not sure if I handle the size argument correctly. Here the snipped from
the man pages:
size This field should be set to the size of the structure in
bytes, as in
sizeof(struct sched_attr). If the provided structure is smaller
than the ker‐
nel structure, any additional fields are assumed to be '0'. If
the provided
structure is larger than the kernel structure, the kernel
verifies that all
additional fields are 0; if they are not, sched_setattr() fails
with the error
E2BIG and updates size to contain the size of the kernel
structure.
The above behavior when the size of the user-space sched_attr
structure does
not match the size of the kernel structure allows for future
extensibility of
the interface. Malformed applications that pass oversize
structures won't
break in the future if the size of the kernel sched_attr
structure is
increased. In the future, it could also allow applications
that know about a
larger user-space sched_attr structure to determine whether they
are running on
an older kernel that does not support the larger structure.
