2010-05-25direct-io: do not merge logically non-contiguous requestsJosef Bacik
Btrfs cannot handle having logically non-contiguous requests submitted. For example if you have Logical: [0-4095][HOLE][8192-12287] Physical: [0-4095] [4096-8191] Normally the DIO code would put these into the same BIO's. The problem is we need to know exactly what offset is associated with what BIO so we can do our checksumming and unlocking properly, so putting them in the same BIO doesn't work. So add another check where we submit the current BIO if the physical blocks are not contigous OR the logical blocks are not contiguous.

2010-05-25direct-io: add a hook for the fs to provide its own submit_bio functionJosef Bacik
Because BTRFS can do RAID and such, we need our own submit hook so we can setup the bio's in the correct fashion, and handle checksum errors properly. So there are a few changes here 1) The submit_io hook. This is straightforward, just call this instead of submit_bio. 2) Allow the fs to return -ENOTBLK for reads. Usually this has only worked for writes, since writes can fallback onto buffered IO. But BTRFS needs the option of falling back on buffered IO if it encounters a compressed extent, since we need to read the entire extent in and decompress it. So if we get -ENOTBLK back from get_block we'll return back and fallback on buffered just like the write case. I've tested these changes with fsx and everything seems to work.

2010-05-25fs: allow short direct-io reads to be completed via buffered IOJosef Bacik
This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or inline extent during DIO, we need to fallback on buffered. If the extent is compressed we need to read the entire thing into memory and de-compress it into the users pages. I have tested this with fsx and everything works great.

2010-05-25fuse: support splice() reading from fuse deviceMiklos Szeredi
Allow userspace filesystem implementation to use splice() to read from the fuse device. The userspace filesystem can now transfer data coming from a WRITE request to an arbitrary file descriptor (regular file, block device or socket) without having to go through a userspace buffer. The semantics of using splice() to read messages are: 1) with a single splice() call move the whole message from the fuse device to a temporary pipe 2) read the header from the pipe and determine the message type 3a) if message is a WRITE then splice data from pipe to destination 3b) else read rest of message to userspace buffer Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2010-05-25fuse: allow splice to move pagesMiklos Szeredi
When splicing buffers to the fuse device with SPLICE_F_MOVE, try to move pages from the pipe buffer into the page cache. This allows populating the fuse filesystem's cache without ever touching the page contents, i.e. zero copy read capability. The following steps are performed when trying to move a page into the page cache: - buf->ops->confirm() to make sure the new page is uptodate - buf->ops->steal() to try to remove the new page from it's previous place - remove_from_page_cache() on the old page - add_to_page_cache_locked() on the new page If any of the above steps fail (non fatally) then the code falls back to copying the page. In particular ->steal() will fail if there are external references (other than the page cache and the pipe buffer) to the page. Also since the remove_from_page_cache() + add_to_page_cache_locked() are non-atomic it is possible that the page cache is repopulated in between the two and add_to_page_cache_locked() will fail. This could be fixed by creating a new atomic replace_page_cache_page() function. fuse_readpages_end() needed to be reworked so it works even if page->mapping is NULL for some or all pages which can happen if the add_to_page_cache_locked() failed. A number of sanity checks were added to make sure the stolen pages don't have weird flags set, etc... These could be moved into generic splice/steal code.

2010-05-25fuse: support splice() writing to fuse deviceMiklos Szeredi
Allow userspace filesystem implementation to use splice() to write to the fuse device. The semantics of using splice() are: 1) buffer the message header and data in a temporary pipe 2) with a *single* splice() call move the message from the temporary pipe to the fuse device The READ reply message has the most interesting use for this, since now the data from an arbitrary file descriptor (which could be a regular file, a block device or a socket) can be tranferred into the fuse device without having to go through a userspace buffer. It will also allow zero copy moving of pages. One caveat is that the protocol on the fuse device requires the length of the whole message to be written into the header. But the length of the data transferred into the temporary pipe may not be known in advance. The current library implementation works around this by using vmplice to write the header and modifying the header after splicing the data into the pipe (error handling omitted): struct fuse_out_header out; iov.iov_base = &out; iov.iov_len = sizeof(struct fuse_out_header); vmsplice(pip[1], &iov, 1, 0); len = splice(input_fd, input_offset, pip[1], NULL, len, 0); /* retrospectively modify the header: */ out.len = len + sizeof(struct fuse_out_header); splice(pip[0], NULL, fuse_chan_fd(req->ch), NULL, out.len, flags); This works since vmsplice only saves a pointer to the data, it does not copy the data itself. Since pipes are currently limited to 16 pages and messages need to be spliced atomically, the length of the data is limited to 15 pages (or 60kB for 4k pages).

2010-05-25fuse: get page reference for readpagesMiklos Szeredi
Acquire a page ref on pages in ->readpages() and release them when the read has finished. Not acquiring a reference didn't seem to cause any trouble since the page is locked and will not be kicked out of the page cache during the read. However the following patches will want to remove the page from the cache so a separate ref is needed. Making the reference in req->pages explicit also makes the code easier to understand.

Patch b7e2ecef92 (perf, trace: Optimize tracepoints by removing IRQ-disable from perf/tracepoint interaction) made the unfortunate mistake of assuming the world is x86 only, correct this. The problem was that perf_fetch_caller_regs() did local_save_flags() into regs->flags, and I re-used that to remove another local_save_flags(), forgetting !x86 doesn't have regs->flags. Do the reverse, remove the local_save_flags() from perf_fetch_caller_regs() and let the ftrace site do the local_save_flags() instead.
