From ebed9ea5b469588c6074f3ed5b8d8ec63c4ccf48 Mon Sep 17 00:00:00 2001 From: Joanne Koong Date: Fri, 14 Aug 2026 11:59:42 -0700 Subject: fuse: add FUSE_IO_URING_CMD_ADD_QUEUE fuse-over-io-uring queues are currently created lazily, as a side effect of the first FUSE_IO_URING_CMD_REGISTER command for a given qid. This ties queue creation to entry registration. Add a FUSE_IO_URING_CMD_ADD_QUEUE command so a server can create a queue explicitly, decoupling queue setup from entry registration. This is additionally a prerequisite for FUSE_IO_URING_CMD_ADD_BUFPOOL, which attaches a buffer pool to an existing queue and therefore needs the queue to have been created first.
