fuse: use iomap for buffered writes

2025-07-17T07:55:15+00:00

Have buffered writes go through iomap. This has two advantages: * granular large folio synchronous reads * granular large folio dirty tracking If for example there is a 1 MB large folio and a write issued at pos 1 to pos 1 MB - 2, only the head and tail pages will need to be read in and marked uptodate instead of the entire folio needing to be read in. Non-relevant trailing pages are also skipped (eg if for a 1 MB large folio a write is issued at pos 1 to 4099, only the first two pages are read in and the ones after that are skipped). iomap also has granular dirty tracking. This is useful in that when it comes to writeback time, only the dirty portions of the large folio will be written instead of having to write out the entire folio. For example if there is a 1 MB large folio and only 2 bytes in it are dirty, only the page for those dirty bytes get written out. Please note that granular writeback is only done once fuse also uses iomap in writeback (separate commit). .release_folio needs to be set to iomap_release_folio so that any allocated iomap ifs structs get freed.

fuse: {io-uring} Handle SQEs - register commands

2025-01-24T10:54:08+00:00

This adds basic support for ring SQEs (with opcode=IORING_OP_URING_CMD). For now only FUSE_IO_URING_CMD_REGISTER is handled to register queue entries. Signed-off-by: Bernd Schubert Reviewed-by: Pavel Begunkov # io_uring Reviewed-by: Luis Henriques Signed-off-by: Miklos Szeredi

fuse: introduce FUSE_PASSTHROUGH capability

2024-02-23T16:36:32+00:00

FUSE_PASSTHROUGH capability to passthrough FUSE operations to backing files will be made available with kernel config CONFIG_FUSE_PASSTHROUGH. When requesting FUSE_PASSTHROUGH, userspace needs to specify the max_stack_depth that is allowed for FUSE on top of backing files. Introduce the flag FOPEN_PASSTHROUGH and backing_id to fuse_open_out argument that can be used when replying to OPEN request, to setup passthrough of io operations on the fuse inode to a backing file. Introduce a refcounted fuse_backing object that will be used to associate an open backing file with a fuse inode. Signed-off-by: Amir Goldstein Signed-off-by: Miklos Szeredi

virtiofs: implement dax read/write operations

2020-09-10T09:39:23+00:00

This patch implements basic DAX support. mmap() is not implemented yet and will come in later patches. This patch looks into implemeting read/write. We make use of interval tree to keep track of per inode dax mappings. Do not use dax for file extending writes, instead just send WRITE message to daemon (like we do for direct I/O path). This will keep write and i_size change atomic w.r.t crash.
