From f791f7c5e354870eaa5e31c4038c6723683283f1 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 29 Jan 2013 16:09:41 -0800 Subject: 9p: Transmit kuid and kgid values Modify the p9_client_rpc format specifiers of every function that directly transmits a uid or a gid from 'd' to 'u' or 'g' as appropriate. Modify those same functions to take kuid_t and kgid_t parameters instead of uid_t and gid_t parameters. Cc: Eric Van Hensbergen Cc: Ron Minnich Cc: Latchesar Ionkov Signed-off-by: Eric W.
