From e1be4a5c03e1b282633e5528ea634c1cc2095c43 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 12 Feb 2019 10:12:28 -0300 Subject: [PATCH] perf beauty ioctl cmd: The 'fd' arg is signed MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It is possible to pass a negative number as the fd and that has to be handled, so stop using 'unsigned int fd' in the ioctl syscall 'cmd' beautifier.
