From 4a7927ff963035548664fbb553f97c16c66e381b Mon Sep 17 00:00:00 2001 From: Julio Montes Date: Mon, 18 Sep 2017 11:46:59 -0500 Subject: [PATCH] NO-UPSTREAM: 9P: always use cached inode to fill in v9fs_vfs_getattr Cherry-pick from kata-container patches: https://github.com/kata-containers/packaging/tree/master/kernel/patches/0001-NO-UPSTREAM-9P-always-use-cached-inode-to-fill-in-v9.patch So that if in cache=none mode, we don't have to lookup server that might not support open-unlink-fstat operation. fixes https://github.com/01org/cc-oci-runtime/issues/47 fixes https://github.com/01org/cc-oci-runtime/issues/1062 Signed-off-by: Julio Montes Signed-off-by: Peng Tao Signed-off-by: Eryu Guan Reviewed-by: Jiufei Xue Reviewed-by: Joseph Qi --- fs/9p/vfs_inode.c | 2 +- fs/9p/vfs_inode_dotl.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/fs/9p/vfs_inode.c b/fs/9p/vfs_inode.c index 72b779bc0942..3125641aaf04 100644 --- a/fs/9p/vfs_inode.c +++ b/fs/9p/vfs_inode.c @@ -1080,7 +1080,7 @@ v9fs_vfs_getattr(const struct path *path, struct kstat *stat, p9_debug(P9_DEBUG_VFS, "dentry: %p\n", dentry); v9ses = v9fs_dentry2v9ses(dentry); - if (v9ses->cache == CACHE_LOOSE || v9ses->cache == CACHE_FSCACHE) { + if (!d_really_is_negative(dentry) || v9ses->cache == CACHE_LOOSE || v9ses->cache == CACHE_FSCACHE) { generic_fillattr(d_inode(dentry), stat); return 0; } diff --git a/fs/9p/vfs_inode_dotl.c b/fs/9p/vfs_inode_dotl.c index a950a927a626..06f911b23a51 100644 --- a/fs/9p/vfs_inode_dotl.c +++ b/fs/9p/vfs_inode_dotl.c @@ -480,7 +480,7 @@ v9fs_vfs_getattr_dotl(const struct path *path, struct kstat *stat, p9_debug(P9_DEBUG_VFS, "dentry: %p\n", dentry); v9ses = v9fs_dentry2v9ses(dentry); - if (v9ses->cache == CACHE_LOOSE || v9ses->cache == CACHE_FSCACHE) { + if (!d_really_is_negative(dentry) || v9ses->cache == CACHE_LOOSE || v9ses->cache == CACHE_FSCACHE) { generic_fillattr(d_inode(dentry), stat); return 0; } -- GitLab
