2026-06-15fuse: remove #include "fuse_i.h" from dev.c and dev_uring.cMiklos Szeredi1-0/+26
Move a couple of function declarations from fuse_i.h to dev.h and fuse_dev_i.h. Add fuse_conn_get_id() helper that retrieves the connection ID (s_dev) from fuse_conn. With the exception of cuse.c, virtio_fs.c and trace.c source files now either include fuse_i.h or fuse_dev_i/dev_uring_i.h but not both. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: set params in fuse_chan_set_initialized()Miklos Szeredi1-1/+7
Set minor, max_write and max_pages in the fuse_chan. These match the same fields in fuse_conn but are needed in both layers. [Dongyang Jin: Pointers should use NULL instead of explicit '0'] Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: create notify.cMiklos Szeredi1-1/+11
Move FUSE_NOTIFY_* handling into a separate source file. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: create poll.cMiklos Szeredi1-0/+2
Move f_op->poll related functions to the new source file. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: change fud->fc to fud->chanMiklos Szeredi1-2/+2
Store pointer to struct fuse_chan instead of struct fuse_conn in fuse_dev. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: split out filesystem part of request sendingMiklos Szeredi1-0/+4
Create a new source file: req.c and add the request sending entry functions: __fuse_simple_request() fuse_simple_background() fuse_simple_notify_reply() Introduce transport layer sending functions that are called by the respective fs layer function: fuse_chan_send() fuse_chan_send_bg() fuse_chan_send_notify_reply() Move calculation of request header fields uid, gid and pid from fuse_get_req() and fuse_force_creads() to a new helper: fuse_fill_creds(). These fileds are now passed to the transport layer via struct fuse_args. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: abort related layering cleanupMiklos Szeredi1-1/+2
- rename fuse_abort_conn() to fuse_chan_abort(), pass fuse_chan pointer instead of fuse_conn - pass an abort_with_err argument that tells fuse_dev_(read|write) to return with ECONNABORTED instead of ENODEV - move fc->aborted to fch->abort_with_err - rename fuse_wait_aborted() to fuse_chan_wait_aborted() Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: remove #include "fuse_i.h" from "req_timeout.c"Miklos Szeredi1-0/+3
Just need to move fuse_abort_conn(). Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move forget related struct and helpersMiklos Szeredi1-0/+5
Move: - struct fuse_forget_link to fuse_dev_i.h - fuse_alloc_forget() to dev.c/dev.h Rename: - fuse_queue_forget -> fuse_chan_queue_forget Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: don't access transport layer structs directly from the fs layerMiklos Szeredi1-0/+27
Add helpers (get and set functions mainly) that cleanly separate the layers. Remove #include "fuse_dev_i.h" from: - inode.c - file.c - control.c Remove #include "dev_uring_i.h" from inode.c. [Li Wang: drop redundant initializer in process_init_limits()] Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move request timeout to fuse_chanMiklos Szeredi1-1/+1
Move: - timeout Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move background queuing related members to fuse_chanMiklos Szeredi1-0/+3
Move: - max_background - num_background - active_background - bg_queue - bg_lock Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move fuse_dev and fuse_pqueue to dev.cMiklos Szeredi1-0/+4
Move function definitions to dev.c, struct definitions to fuse_dev_i.h. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move fuse_iqueue to fuse_chanMiklos Szeredi1-0/+2
Move the 'fiq' member from fuse_conn to fuse_chan. Move iqueue related structure definitions and function declarations from "fuse_i.h" to "fuse_dev_i.h". Add a fuse_dev_chan_new() helper, that returns a fuse_chan initialized with the fuse_dev_fiq_ops. Add a fuse_chan_release() function, that calls fiq->ops->release(). Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: add struct fuse_chanMiklos Szeredi1-0/+7
The goal is to separate transport layer stuff out from struct fuse_conn, leaving just the filesystem related members. Add a new object referenced from fuse_conn. This patch just implements the allocation and freeing of this object. Following patches will move transport related members from fuse_conn to fuse_chan. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-06-15fuse: move request timeout code to a new source fileMiklos Szeredi1-0/+10
This marks the first step in cleanly separating the transport layer from the filesystem layer. Add "dev.h", which will contain the interface definition for the transport layer. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
