From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Simmons Date: Thu, 27 Feb 2020 16:11:55 -0500 Subject: [lustre-devel] [PATCH 247/622] lustre: misc: remove LIBCFS_IOC_DEBUG_MASK ioctl In-Reply-To: <1582838290-17243-1-git-send-email-jsimmons@infradead.org> References: <1582838290-17243-1-git-send-email-jsimmons@infradead.org> Message-ID: <1582838290-17243-248-git-send-email-jsimmons@infradead.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lustre-devel@lists.lustre.org From: Andreas Dilger Remove the LIBCFS_IOC_DEBUG_MASK ioctl, since the debug and subsystem mask can be modified via sysfs for a long time, and tools have not used this ioctl since 2.6.
