| parent | staging: lustre: clio: Reduce memory overhead of per-page allocation (diff) | |
staging: lustre: osc: revise unstable pages accounting
A few changes are made in this patch for unstable pages tracking:
1. Remove kernel NFS unstable pages tracking because it killed
performance
2. Track unstable pages as part of LRU cache. Otherwise Lustre
can use much more memory than max_cached_mb
3. Remove obd_unstable_pages tracking to avoid using global
atomic counter
4. Make unstable pages track optional. Tracking unstable pages is
turned off by default, and can be controlled by
llite.*.unstable_stats.
