  "message": "fuse: enable dynamic configuration of fuse max pages limit (FUSE_MAX_MAX_PAGES)\n\nIntroduce the capability to dynamically configure the max pages limit\n(FUSE_MAX_MAX_PAGES) through a sysctl. This allows system administrators\nto dynamically set the maximum number of pages that can be used for\nservicing requests in fuse.\n\nPreviously, this is gated by FUSE_MAX_MAX_PAGES which is statically set\nto 256 pages. One result of this is that the buffer size for a write\nrequest is limited to 1 MiB on a 4k-page system.\n\nThe default value for this sysctl is the original limit (256 pages).\n\n$ sysctl -a | grep max_pages_limit\nfs.fuse.max_pages_limit \u003d 256\n\n$ sysctl -n fs.fuse.max_pages_limit\n256\n\n$ echo 1024 | sudo tee /proc/sys/fs/fuse/max_pages_limit\n1024\n\n$ sysctl -n fs.fuse.max_pages_limit\n1024\n\n$ echo 65536 | sudo tee /proc/sys/fs/fuse/max_pages_limit\ntee: /proc/sys/fs/fuse/max_pages_limit: Invalid argument\n\n$ echo 0 | sudo tee /proc/sys/fs/fuse/max_pages_limit\ntee: /proc/sys/fs/fuse/max_pages_limit: Invalid argument\n\n$ echo 65535 | sudo tee /proc/sys/fs/fuse/max_pages_limit\n65535\n\n$ sysctl -n fs.fuse.max_pages_limit\n65535\n\nBUG\u003db/496012319\nTEST\u003dpresubmit\nRELEASE_NOTE\u003dEnabled dynamic configuration of FUSE max pages limit.\n\ncos-patch: bug\nSigned-off-by: Joanne Koong \u003cjoannelkoong@gmail.com\u003e\nReviewed-by: Josef Bacik \u003cjosef@toxicpanda.com\u003e\nReviewed-by: Sweet Tea Dorminy \u003csweettea-kernel@dorminy.me\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@redhat.com\u003e\nChange-Id: I49200c2f1fbecd8ea4a498595381ef5cc0ab3545\nReviewed-on: https://cos-review.googlesource.com/c/third_party/kernel/+/139702\nTested-by: Cusky Presubmit Bot \u003cpresubmit@cos-infra-prod.iam.gserviceaccount.com\u003e\nReviewed-by: Derek Taylor \u003cddtaylor@google.com\u003e\n",
