List-Unsubscribe: , List-Archive: This patch defines exp_pseudoroot(), which is used to set the filehandle for the root of the pseudofs. Right now, we just use the root of an arbitrarily-selected export. This is just a placeholder until the pseudofs is properly implemented in 2.5. --- old/include/linux/nfsd/export.h Wed Jul 24 16:03:17 2002 +++ new/include/linux/nfsd/export.h Mon Jul 29 11:50:09 2002 @@ -101,6 +101,7 @@ struct svc_export * exp_get_by_name(stru struct dentry *dentry); int exp_rootfh(struct svc_client *, char *path, struct knfsd_fh *, int maxsize); +int exp_pseudoroot(struct svc_client *, struct svc_fh *fhp); int nfserrno(int errno); void exp_nlmdetach(void); --- old/fs/nfsd/export.c Wed Jul 24 16:03:29 2002 +++ new/fs/nfsd/export.c Mon Jul 29 11:50:09 2002 @@ -498,6 +498,24 @@ out: return err; } +/* + * Called when we need the filehandle for the root of the pseudofs, + * for a given NFSv4 client.
