From: Jeff Layton Date: Mon, 3 Feb 2014 17:13:09 +0000 (-0500) Subject: locks: report l_pid as -1 for FL_FILE_PVT locks X-Git-Tag: v3.15-rc1~98^2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3fd80cddc6af5ba53244514a61450d4b30a9fb9d;p=pandora-kernel.git locks: report l_pid as -1 for FL_FILE_PVT locks FL_FILE_PVT locks are no longer tied to a particular pid, and are instead inheritable by child processes. Report a l_pid of '-1' for these sorts of locks since the pid is somewhat meaningless for them. This precedent comes from FreeBSD. There, POSIX and flock() locks can conflict with one another. If fcntl(F_GETLK, ...) returns a lock set with flock() then the l_pid member cannot be a process ID because the lock is not held by a process as such. Acked-by: J.
