    [PATCH] RPC,NFS: new rpc_pipefs patch · 278c995c
    Christoph Hellwig 提交于
     Currently rpc_mkdir/rpc_rmdir and rpc_mkpipe/mk_unlink have an API that's
     a little unfortunate.  They take a path relative to the rpc_pipefs root and
     thus need to perform a full lookup.  If you look at debugfs or usbfs they
     always store the dentry for directories they created and thus can pass in
     a dentry + single pathname component pair into their equivalents of the
     above functions.
    
     And in fact rpc_pipefs actually stores a dentry for all but one component so
     this change not only simplifies the core rpc_pipe code but also the callers.
    
     Unfortuntately this code path is only used by the NFS4 idmapper and
     AUTH_GSSAPI for which I don't have a test enviroment.  Could someone give
     it a spin?  It's the last bit needed before we can rework the
     lookup_hash API
