That\nleaves us with possible changes of global data structures.

We\ncurrently have global shrinkers for the inode and dentry caches that\nsplit up into per-superblock operations via a coarse proportioning\nmethod that does not batch very well.  The global shrinkers also\nhave a dependency - dentries pin inodes - so we have to be very\ncareful about how we register the global shrinkers so that the\nimplicit call order is always correct.\n\nWith a per-sb shrinker callout, we can encode this dependency\ndirectly into the per-sb shrinker, hence avoiding the need for\nstrictly ordering shrinker registrations.

      "message": "vmscan: reduce wind up shrinker-\u003enr when shrinker can\u0027t do work\n\nWhen a shrinker returns -1 to shrink_slab() to indicate it cannot do\nany work given the current memory reclaim requirements, it adds the\nentire total_scan count to shrinker-\u003enr. The idea ehind this is that\nwhenteh shrinker is next called and can do work, it will do the work\nof the previously aborted shrinker call as well.\n\nHowever, if a filesystem is doing lots of allocation with GFP_NOFS\nset, then we get many, many more aborts from the shrinkers than we\ndo successful calls. The result is that shrinker-\u003enr winds up to\nit\u0027s maximum permissible value (twice the current cache size) and\nthen when the next shrinker call that can do work is issued, it\nhas enough scan count built up to free the entire cache twice over.\n\nThis manifests itself in the cache going from full to empty in a\nmatter of seconds, even when only a small part of the cache is\nneeded to be emptied to free sufficient memory.\n\nUnder metadata intensive workloads on ext4 and XFS, I\u0027m seeing the\nVFS caches increase memory consumption up to 75% of memory (no page\ncache pressure) over a period of 30-60s, and then the shrinker\nempties them down to zero in the space of 2-3s. This cycle repeats\nover and over again, with the shrinker completely trashing the inode\nand dentry caches every minute or so the workload continues.\n\nThis behaviour was made obvious by the shrink_slab tracepoints added\nearlier in the series, and made worse by the patch that corrected\nthe concurrent accounting of shrinker-\u003enr.\n\nTo avoid this problem, stop repeated small increments of the total\nscan value from winding shrinker-\u003enr up to a value that can cause\nthe entire cache to be freed. We still need to allow it to wind up,\nso use the delta as the \"large scan\" threshold check - if the delta\nis more than a quarter of the entire cache size, then it is a large\nscan and allowed to cause lots of windup because we are clearly\nneeding to free lots of memory.\n\nIf it isn\u0027t a large scan then limit the total scan to half the size\nof the cache so that windup never increases to consume the whole\ncache. Reducing the total scan limit further does not allow enough\nwind-up to maintain the current levels of performance, whilst a\nhigher threshold does not prevent the windup from freeing the entire\ncache under sustained workloads.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n"
