Re: [RESEND PATCH] sched/syscalls: Allow setting niceness using sched_param struct

Hi Peter,

Have I addressed your concerns?

In my opinion, this is a simple change that adds ABI functionality, without affecting any other parts of the syscalls involved, whether breaking or non-breaking.

Like I said in previous replies, POSIX doesn't allow passing a negative number as a successful value, and setting the static priority directly can expose the scheduler to invalid priority values for CFS policies in later syscalls.

As far as I can see, this is the only way for usage of posix_spawnattr_setschedparam() to be both compliant _and_ functional for SCHED_NORMAL and SCHED_BATCH.

-- Thanks for your time, MCP
