From b48dbb998d70b7f48c2ec0a15c3cf47136808e4e Mon Sep 17 00:00:00 2001 From: Dominique Martinet Date: Sun, 12 Jun 2022 13:42:32 +0900 Subject: 9p fid refcount: add p9_fid_get/put wrappers I was recently reminded that it is not clear that p9_client_clunk() was actually just decrementing refcount and clunking only when that reaches zero: make it clear through a set of helpers. This will also allow instrumenting refcounting better for debugging next patch Link: https://lkml.kernel.org/r/20220612085330.1451496-5-asmadeus@codewreck.org Reviewed-by: Tyler Hicks Reviewed-by: Christian Schoenebeck Signed-off-by: Dominique Martinet --- fs/9p/vfs_dentry.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'fs/9p/vfs_dentry.c') diff --git a/fs/9p/vfs_dentry.c b/fs/9p/vfs_dentry.c index 1c609e99d280..f89f01734587 100644 --- a/fs/9p/vfs_dentry.c +++ b/fs/9p/vfs_dentry.c @@ -54,7 +54,7 @@ static void v9fs_dentry_release(struct dentry *dentry) p9_debug(P9_DEBUG_VFS, " dentry: %pd (%p)\n", dentry, dentry); hlist_for_each_safe(p, n, (struct hlist_head *)&dentry->d_fsdata) - p9_client_clunk(hlist_entry(p, struct p9_fid, dlist)); + p9_fid_put(hlist_entry(p, struct p9_fid, dlist)); dentry->d_fsdata = NULL; } @@ -85,7 +85,7 @@ static int v9fs_lookup_revalidate(struct dentry *dentry, unsigned int flags) retval = v9fs_refresh_inode_dotl(fid, inode); else retval = v9fs_refresh_inode(fid, inode); - p9_client_clunk(fid); + p9_fid_put(fid); if (retval == -ENOENT) return 0; -- cgit v1.2.3-70-g09d2
