This fixes all the NFS related latency problems I was seeing. Now the longest latency from an NFS kernel compile with "make -j64" is 391 usecs in get_swap_page.


great! The latest patches (-42-08 and later) have the reworked nfs_scan_list() lock-breaker, which should perform similarly.

i bet these NFS patches also improve generic NFS performance on fast networks. I've attached the full patchset with all fixes and improvements included - might be worth a try in -mm?


Just a question - would these changes be expected to improve NFS client *read* access at all, or just write?

Thanks!
