From a02d51919b05a5b5b237012b3e6ea738bc533b08 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Mon, 13 Jul 2026 21:25:21 +0200 Subject: [PATCH] dm-ioctl: delete a useless condition The condition "remaining <= 0" can never be true. The variable remaining has type size_t, thus it can't be negative. It can't be zero because we made sure earlier that "remaining > sizeof(struct dm_target_spec)" and then we added "sizeof(struct dm_target_spec)" to "outptr" (this means that we subtraceted "sizeof(struct dm_target_spec)" from "remaining").
