From b10a4a9f7695335bd2bb19bffdda7fbefbc6581f Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 9 Jul 2018 02:29:58 -0400 Subject: [PATCH] create_pipe_files(): use fput() if allocation of the second file fails ... just use put_pipe_info() to get the pipe->files down to 1 and let fput()-called pipe_release() do freeing.
