From: Johannes Weiner Date: Thu, 16 Nov 2017 01:38:34 +0000 (-0800) Subject: fs: fuse: account fuse_inode slab memory as reclaimable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df206988e03e8510e08b2ee77f3e65010ed97768;p=linux.git fs: fuse: account fuse_inode slab memory as reclaimable Fuse inodes are currently included in the unreclaimable slab counts - SUnreclaim in /proc/meminfo, slab_unreclaimable in /proc/vmstat and the per-cgroup memory.stat. But they are reclaimable just like other filesystems' inodes, and /proc/sys/vm/drop_caches frees them easily. Mark the slab cache reclaimable.
