sys/fs/nullfs null_vfsops.c
Log:
Reflect mpsafety of the underlying filesystem in the nullfs image.
I benchmarked this by simultaneously extracting 4 large tarballs (basically
world images) on a 4-processor AMD64 system, in a malloc-backed md.
With this patch, system time was reduced by 43%, and wall clock time by 33%.
