This patch improves the sys_select() execution when used for delay.
Please describe what aspect of the syscall is improved. Is this only
speeding up the execution for the delay case while slowing down
the normal case, or do the actual semantics improve?
It appears to simply speed up the delay case.
One thing that I noticed though--the patch had the following line:
if ((n == 0) && (inp == NULL) && (outp == NULL) && (exp == NULL)) {
Would it be enought to just do the following?
if (n == 0) {
Given that if any of the fd_set pointers are non-empty, "n" ought to be
non-zero, would this be a sufficient check?
