Sun, 21 Jun 2026 13:19:04 +0000 (UTC) Date: Sun, 21 Jun 2026 22:18:49 +0900 From: Dominique Martinet To: Linus Torvalds Cc: Christian Schoenebeck , Eric Van Hensbergen , v9fs@lists.linux.dev, linux-kernel@vger.kernel.org Subject: [GIT PULL] 9p fixes for 7.2-rc1 Message-ID: Precedence: bulk X-Mailing-List: v9fs@lists.linux.dev List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Hi Linus, same report as usual with barely keeping up: there's actually another half a dozen of LLM patches I didn't pick up for this cycle and will try to find time to review for next one, and I'm not as happy as I want to be about how thoroughly I've checked the patches that did get in (please let me know if you'd rather I drop the "fix infinite loop in p9_client_rpc on fatal signal" patch I mentioned in the tag, I think the patch should be ok, but I don't necessarily judge the risk the same as you would) The commit date being a bit earlier today was just me dropping a commit I hadn't intended to send, nothing else was reworked recently. ------- The following changes since commit 8fc518e489c1386fd0cf7f4256d055960ed6a2e4: 9p/trans_xen: replace simple_strto* with kstrtouint (2026-04-16 02:57:01 +0000) are available in the Git repository at: https://github.com/martinetd/linux tags/9p-for-7.2-rc1 for you to fetch changes up to aa88278693cbfaf7a2acf961379973fbb63b165c: 9p: Add missing read barrier in virtio zero-copy path (2026-06-21 05:22:57 +0000) ---------------------------------------------------------------- Asides of the avalanche of LLM-driven fixes, there are a couple of big changes this cycle: - negative dentry and symlink cache - a way out of the unkillable "io_wait_event_killable" (because it looped around waiting for the request flush to come back from server; this has been bugging syzcaller folks since forever): I'm still not 100% sure about this patch, but I think it's as good as we'll ever get, and will keep testing a bit further in the coming weeks The rest is more noisy than usual, but shouldn't cause any trouble. ---------------------------------------------------------------- Aayush Patil (1): docs/filesystems/9p: fix broken external links Breno Leitao (1): 9p: skip nlink update in cacheless mode to fix WARN_ON Christophe JAILLET (1): net/9p/usbg: Constify struct configfs_item_operations David Laight (1): net/9p: Replace strlen() strcpy() pair with strscpy() Dominique Martinet (1): 9p: v9fs_file_do_lock: replace WARN_ONCE with p9_debug Gui-Dong Han (1): 9p: Add missing read barrier in virtio zero-copy path Hongling Zeng (1): 9p: avoid returning ERR_PTR(0) from mkdir operations Pierre Barre (2): 9p: use kvzalloc for readdir buffer 9p: invalidate readdir buffer on seek Remi Pommarel (4): 9p: Cache negative dentries for lookup performance 9p: Add mount option for negative dentry cache retention 9p: Set default negative dentry retention time for cache=loose 9p: Enable symlink caching in page cache Vasiliy Kovalev (1): net/9p: fix infinite loop in p9_client_rpc on fatal signal Yizhou Zhao (2): 9p: avoid putting oldfid in p9_client_walk() error path net/9p: fix race condition on rdma->state in trans_rdma.c Documentation/filesystems/9p.rst | 10 +++++--- fs/9p/fid.c | 11 +++++---- fs/9p/v9fs.c | 27 ++++++++++++++++++++- fs/9p/v9fs.h | 28 +++++++++++++-------- fs/9p/v9fs_vfs.h | 15 ++++++++++++ fs/9p/vfs_addr.c | 36 +++++++++++++++++++++++++-- fs/9p/vfs_dentry.c | 105 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++----------- fs/9p/vfs_dir.c | 14 ++++++++++- fs/9p/vfs_file.c | 2 +- fs/9p/vfs_inode.c | 46 ++++++++++++++++++++--------------- fs/9p/vfs_inode_dotl.c | 58 ++++++++++++++++++++++++++++++++++++++------ fs/9p/vfs_super.c | 1 + include/net/9p/client.h | 2 ++ net/9p/client.c | 7 ++++-- net/9p/trans_fd.c | 6 ++--- net/9p/trans_rdma.c | 19 +++++++++++++-- net/9p/trans_usbg.c | 2 +- net/9p/trans_virtio.c | 5 ++++ 18 files changed, 320 insertions(+), 74 deletions(-) -- Dominique Martinet | Asmadeus
