The semantics of using splice() are:\n\n 1) buffer the message header and data in a temporary pipe\n 2) with a *single* splice() call move the message from the temporary pipe\n to the fuse device\n\nThe READ reply message has the most interesting use for this, since\nnow the data from an arbitrary file descriptor (which could be a\nregular file, a block device or a socket) can be tranferred into the\nfuse device without having to go through a userspace buffer. It will\nalso allow zero copy moving of pages.\n\nOne caveat is that the protocol on the fuse device requires the length\nof the whole message to be written into the header. But the length of\nthe data transferred into the temporary pipe may not be known in\nadvance. The current library implementation works around this by\nusing vmplice to write the header and modifying the header after\nsplicing the data into the pipe (error handling omitted):\n\n\tstruct fuse_out_header out;\n\n\tiov.iov_base \u003d \u0026out;\n\tiov.iov_len \u003d sizeof(struct fuse_out_header);\n\tvmsplice(pip[1], \u0026iov, 1, 0);\n\tlen \u003d splice(input_fd, input_offset, pip[1], NULL, len, 0);\n\t/* retrospectively modify the header: */\n\tout.len \u003d len + sizeof(struct fuse_out_header);\n\tsplice(pip[0], NULL, fuse_chan_fd(req-\u003ech), NULL, out.len, flags);\n\nThis works since vmsplice only saves a pointer to the data, it does\nnot copy the data itself.\n\nSince pipes are currently limited to 16 pages and messages need to be\nspliced atomically, the length of the data is limited to 15 pages (or\n60kB for 4k pages).\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "1bf94ca73ea524228b864275efa44373ebb939a0", "tree": "6ad0f17f4da1f1dd8a1aae2c77e5865fb5f42f33", "parents": [ "4aa0edd294f69e3100973a0ecfa1e6b5ab42d83a" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Tue May 25 15:06:06 2010 +0200" }, "committer": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Tue May 25 15:06:06 2010 +0200" }, "message": "fuse: use get_user_pages_fast()\n\nReplace uses of get_user_pages() with get_user_pages_fast().

I\u0027d claim that they\n are almost impossible, unless you limit them somehow (shared\n writable mappings are the nastiest part - if you don\u0027t have those,\n you can reasonably limit your problems by limiting the number of\n dirty pages you accept through normal \"write()\" calls).\"\n\nInstead of attempting the impossible, I\u0027ve just waited for the dirty page\naccounting infrastructure to materialize (thanks to Peter Zijlstra and\nothers). This nicely solved the biggest problem: limiting the number of pages\nused for write caching.\n\nSome small details remained, however, which this largish patch attempts to\naddress. It provides a page writeback implementation for fuse, which is\ncompletely safe against VM related deadlocks. Performance may not be very\ngood for certain usage patterns, but generally it should be acceptable.\n\nIt has been tested extensively with fsx-linux and bash-shared-mapping.\n\nFuse page writeback design\n--------------------------\n\nfuse_writepage() allocates a new temporary page with GFP_NOFS|__GFP_HIGHMEM.\nIt copies the contents of the original page, and queues a WRITE request to the\nuserspace filesystem using this temp page.\n\nThe writeback is finished instantly from the MM\u0027s point of view: the page is\nremoved from the radix trees, and the PageDirty and PageWriteback flags are\ncleared.\n\nFor the duration of the actual write, the NR_WRITEBACK_TEMP counter is\nincremented. The per-bdi writeback count is not decremented until the actual\nwrite completes.\n\nOn dirtying the page, fuse waits for a previous write to finish before\nproceeding. This makes sure, there can only be one temporary page used at a\ntime for one cached page.\n\nThis approach is wasteful in both memory and CPU bandwidth, so why is this\ncomplication needed?\n\nThe basic problem is that there can be no guarantee about the time in which\nthe userspace filesystem will complete a write. It may be buggy or even\nmalicious, and fail to complete WRITE requests. We don\u0027t want unrelated parts\nof the system to grind to a halt in such cases.\n\nAlso a filesystem may need additional resources (particularly memory) to\ncomplete a WRITE request. There\u0027s a great danger of a deadlock if that\nallocation may wait for the writepage to finish.\n\nCurrently there are several cases where the kernel can block on page\nwriteback:\n\n - allocation order is larger than PAGE_ALLOC_COSTLY_ORDER\n - page migration\n - throttle_vm_writeout (through NR_WRITEBACK)\n - sync(2)\n\nOf course in some cases (fsync, msync) we explicitly want to allow blocking.\nSo for these cases new code has to be added to fuse, since the VM is not\ntracking writeback pages for us any more.\n\nAs an extra safetly measure, the maximum dirty ratio allocated to a single\nfuse filesystem is set to 1% by default. This way one (or several) buggy or\nmalicious fuse filesystems cannot slow down the rest of the system by hogging\ndirty memory.\n\nWith appropriate privileges, this limit can be raised through\n\u0027/sys/class/bdi/\u003cbdi\u003e/max_ratio\u0027.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d12def1bcb809b6172ee207a24e00a0a4398df1d", "tree": "96e151de1e80cacd9202a00b77654533a9754207", "parents": [ "b57d426445c98789265de6a9338cdb06462d15fb" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Feb 06 01:38:39 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Feb 06 10:41:13 2008 -0800" }, "message": "fuse: limit queued background requests\n\nLibfuse basically creates a new thread for each new request.
