fuse: fuse_dev_i.h: clean up kernel-doc warnings

2026-06-15T12:06:18+00:00

Change some "/**" to "/*" since they are not kernel-doc comments: Warning: fs/fuse/fuse_dev_i.h:25 This comment starts with '/**', but isn't a kernel-doc comment. Refer to Documentation/doc-guide/kernel-doc.rst * Request flags Warning: fs/fuse/fuse_dev_i.h:58 This comment starts with '/**', but isn't a kernel-doc comment. Refer to Documentation/doc-guide/kernel-doc.rst * A request to the client Warning: fs/fuse/fuse_dev_i.h:117 This comment starts with '/**', but isn't a kernel-doc comment. Refer to Documentation/doc-guide/kernel-doc.rst * Input queue callbacks Warning: fs/fuse/fuse_dev_i.h:289 This comment starts with '/**', but isn't a kernel-doc comment. Refer to Documentation/doc-guide/kernel-doc.rst * Fuse device instance and more like this. Convert enum fuse_req_flag to kernel-doc format. Convert struct fuse_req, struct fuse_iqueue_ops, and struct fuse_dev to kernel-doc format. These warnings remain: Warning: fs/fuse/fuse_dev_i.h:115 struct member 'ring_entry' not described in 'fuse_req' Warning: fs/fuse/fuse_dev_i.h:115 struct member 'ring_queue' not described in 'fuse_req' Binary build output is the same before and after these changes.

fuse: alloc pqueue before installing fch in fuse_dev

2026-06-15T12:06:18+00:00

Prior to this patchset, fuse_dev (containing fuse_pqueue) was allocated on mount. But now fuse_dev is allocated when opening /dev/fuse, even though the queues are not needed at that time. Delay allocation of the pqueue (4k worth of list_head) just before mounting or cloning a device. Various distributions (e.g. Debian/Fedora) configure /dev/fuse as world writable, so the pqueue allocation should be deferred to a privileged operation (mount) to prevent unprivileged userspace from consuming pinned kernel memory.

fuse: remove #include "fuse_i.h" from dev.c and dev_uring.c

2026-06-15T12:06:18+00:00

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

fuse: set params in fuse_chan_set_initialized()

2026-06-15T12:06:17+00:00

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

fuse: create notify.c

2026-06-15T12:06:17+00:00

Move FUSE_NOTIFY_* handling into a separate source file. Signed-off-by: Miklos Szeredi

fuse: change fud->fc to fud->chan

2026-06-15T12:06:17+00:00

fuse: change req->fm to req->chan

2026-06-15T12:06:17+00:00

fuse: abort related layering cleanup

2026-06-15T12:06:17+00:00

- 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

fuse: remove #include "fuse_i.h" from "dev_uring_i.h"

2026-06-15T12:06:16+00:00

fuse: move fuse_dev_waitq to dev.c

2026-06-15T12:06:16+00:00

Move wake_up_all(&fuse_dev_waitq) into fuse_dev_install() where it logically belongs. Signed-off-by: Miklos Szeredi
