Modified files:
sys/kern kern_descrip.c
Log:
Two minor optimizations of fdalloc():
- if minfd < fd_freefile (as is most often the case, since minfd is
usually 0), set it to fd_freefile.
- remove a call to fd_first_free() which duplicates work already done
by fdused().
This change results in a small but measurable speedup for processes
with large numbers (several thousands) of open files.
