Merge tag '9p-for-6.7-rc1' of https://github.com/martinetd/linux
Pull 9p updates from Dominique Martinet: A bunch of small fixes: - three W=1 warning fixes: the NULL -> "" replacement isn't trivial but is serialized identically by the protocol layer and has been tested - one syzbot/KCSAN datarace annotation where we don't care about users messing with the fd they passed to mount -t 9p - removing a declaration without implementation - yet another race fix for trans_fd around connection close: the 'err' field is also used in potentially racy calls and this isn't complete, but it's better than what we had - and finally a theorical memory leak fix on serialization failure" * tag '9p-for-6.7-rc1' of https://github.com/martinetd/linux: 9p/net: fix possible memory leak in p9_check_errors() 9p/fs: add MODULE_DESCRIPTION 9p/net: xen: fix false positive printf format overflow warning 9p: v9fs_listxattr: fix %s null argument warning 9p/trans_fd: Annotate data-racy writes to file::f_flags fs/9p: Remove unused function declaration v9fs_inode2stat() 9p/trans_fd: avoid sending req to a cancelled conn
