Subject: [PATCH v2 01/13] selftests/resctrl: Convert get_mem_bw_imc() fd close to for loop
Date: Mon, 11 Mar 2024 15:52:18 +0200	[thread overview]
Message-ID: <20240311135230.7007-2-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20240311135230.7007-1-ilpo.jarvinen@linux.intel.com>

The open() side handles fds in a for loop but close() is based on two
fixed indexes READ and WRITE.

Match the close() side with the open() side by using for loop for
consistency.
