From 4bc46c047ecf1818e6a053fbb399aab9c476c16d Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Tue, 10 Oct 2023 18:04:41 -0400 Subject: [PATCH] fs: dlm: Simplify buffer size computation in dlm_create_debug_file() [ Upstream commit 19b3102c0b5350621e7492281f2be0f071fb7e31 ] Use sizeof(name) instead of the equivalent, but hard coded, DLM_LOCKSPACE_LEN + 8. This is less verbose and more future proof.
