fs/9p: remove unnecessary invalidate_inode_pages2

2023-08-03T08:26:12Z

commit 350cd9b959757e7c571f45fab29d116d5f67cbff upstream. There was an invalidate_inode_pages2 added to readonly mmap path that is unnecessary since that path is only entered when writeback cache is disabled on mount.

fs/9p: fix type mismatch in file cache mode helper

2023-08-03T08:26:12Z

commit 09430aba3a9ffd986834614a3406a13588170bde upstream. There were two flags (s_flags and s_cache) which had incorrect signed type in the parameters of the file cache mode helper function.

fs/9p: fix typo in comparison logic for cache mode

2023-08-03T08:26:11Z

commit 878cb3e0337d7c3096aee301a2a3cd358dc8aa81 upstream. There appears to be a typo in the comparison statement for the logic which sets a file's cache mode based on mount flags.

fs/9p: remove unnecessary and overrestrictive check

2023-08-03T08:26:11Z

commit 75b396821cb71164dac3a1ad51dda4781ea8dbad upstream. This eliminates a check for shared that was overrestrictive and prevented read-only mmaps when writeback caches weren't enabled.

[ Upstream commit 95f41d87810083d8b3dedcce46a4e356cf4a9673 ] The commit in Fixes has introduced some "enum p9_session_flags" values larger than a char. Such values are stored in "v9fs_session_info->flags" which is a char only. Turn it into an int so that the "enum p9_session_flags" values can fit in it.

Pull 9p updates from Eric Van Hensbergen: "This includes a number of patches that didn't quite make the cut last merge window while we addressed some outstanding issues and review comments. It includes some new caching modes for those that only want readahead caches and reworks how we do writeback caching so we are not keeping extra references around which both causes performance problems and uses lots of additional resources on the server. It also includes a new flag to force disabling of xattrs which can also cause major performance issues, particularly if the underlying filesystem on the server doesn't support them. Finally it adds a couple of additional mount options to better support directio and enabling caches when the server doesn't support qid.version. There was one late-breaking bug report that has also been included as its own patch where I forgot to propagate an embarassing bit-logic fix to the various variations of open" * tag '9p-6.4-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs: fs/9p: Fix bit operation logic error fs/9p: Rework cache modes and add new options to Documentation fs/9p: remove writeback fid and fix per-file modes fs/9p: Add new mount modes 9p: Add additional debug flags and open modes fs/9p: allow disable of xattr support on mount fs/9p: Remove unnecessary superblock flags fs/9p: Consolidate file operations and add readahead and writeback

9p: Remove INET dependency

2023-05-04T20:46:57Z

9pfs can run over assorted transports, so it doesn't have an INET dependency. Drop it and remove the includes of linux/inet.h. NET_9P_FD/trans_fd.o builds without INET or UNIX and is usable over plain file descriptors. However, tcp and unix functionality is still built and would generate runtime failures if used. Add imply INET and UNIX to NET_9P_FD, so functionality is enabled by default but can still be explicitly disabled. This allows configuring 9pfs over Xen with INET and UNIX disabled.

fs/9p: Fix bit operation logic error

2023-04-28T16:59:26Z

This re-introduces a fix that somehow got dropped during rebase of the current series in for-next. When writeback is enabled, opens are forced to support both read and write operations but with the logic error other flags may be dropped unintentionaly.
