From: Bryan Schumaker Date: Wed, 29 Sep 2010 19:41:49 +0000 (-0400) Subject: NFS: new idmapper X-Git-Tag: v2.6.37-rc1~120^2~30 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=955a857e062642cd3ebe1dc7bb38c0f85d8f8f17;p=pandora-kernel.git NFS: new idmapper This patch creates a new idmapper system that uses the request-key function to place a call into userspace to map user and group ids to names. The old idmapper was single threaded, which prevented more than one request from running at a single time. This means that a user would have to wait for an upcall to finish before accessing a cached result. The upcall result is stored on a keyring of type id_resolver. See the file Documentation/filesystems/nfs/idmapper.txt for instructions.
