Mateusz Guzik 4cace859c2 vfs: convert struct mount counters to per-cpu ... There are 3 counters modified all the time in this structure - one for keeping the structure alive, one for preventing unmount and one for tracking active writers. Exact values of these counters are very rarely needed, which makes them a prime candidate for conversion to a per-cpu scheme, resulting in much better performance. Sample benchmark performing fstatfs (modifying 2 out of 3 counters) on a 104-way 2 socket Skylake system: before: 852393 ops/s after: 76682077 ops/s Reviewed by: kib, jeff Tested by: pho Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D21637		2019-09-16 21:37:47 +00:00
