From 1c3c07e9f6cc50dab2aeb8051325e317d4f6c70e Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 25 Jul 2006 11:28:18 -0400 Subject: NFS: Add a new ACCESS rpc call cache to the linux nfs client The current access cache only allows one entry at a time to be cached for each inode. Add a per-inode red-black tree in order to allow more than one to be cached at a time. Should significantly cut down the time spent in path traversal for shared directories such as ${PATH}, /usr/share, etc. Signed-off-by: Trond Myklebust --- fs/nfs/inode.c | 13 ++++--------- 1 file changed, 4 insertions(+), 9 deletions(-) (limited to 'fs/nfs/inode.c') diff --git a/fs/nfs/inode.c b/fs/nfs/inode.c index d349fb2245da..b94ab060bb1e 100644 --- a/fs/nfs/inode.c +++ b/fs/nfs/inode.c @@ -76,19 +76,14 @@ int nfs_write_inode(struct inode *inode, int sync) void nfs_clear_inode(struct inode *inode) { - struct nfs_inode *nfsi = NFS_I(inode); - struct rpc_cred *cred; - /* * The following should never happen... */ BUG_ON(nfs_have_writebacks(inode)); - BUG_ON (!list_empty(&nfsi->open_files)); + BUG_ON(!list_empty(&NFS_I(inode)->open_files)); + BUG_ON(atomic_read(&NFS_I(inode)->data_updates) != 0); nfs_zap_acl_cache(inode); - cred = nfsi->cache_access.cred; - if (cred) - put_rpccred(cred); - BUG_ON(atomic_read(&nfsi->data_updates) != 0); + nfs_access_zap_cache(inode); } /** @@ -290,7 +285,7 @@ nfs_fhget(struct super_block *sb, struct nfs_fh *fh, struct nfs_fattr *fattr) nfsi->attrtimeo = NFS_MINATTRTIMEO(inode); nfsi->attrtimeo_timestamp = jiffies; memset(nfsi->cookieverf, 0, sizeof(nfsi->cookieverf)); - nfsi->cache_access.cred = NULL; + nfsi->access_cache = RB_ROOT; unlock_new_inode(inode); } else -- cgit v1.2.3
