Subject: [Cluster-devel] [PATCH RESEND 1/8] fs: dlm: Simplify buffer size computation in dlm_create_debug_file()
Date: Tue, 10 Oct 2023 18:04:41 -0400 [thread overview]
Message-ID: <20231010220448.2978176-1-aahringo@redhat.com> (raw)
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
Use sizeof(name) instead of the equivalent, but hard coded,
DLM_LOCKSPACE_LEN + 8.
This is less verbose and more future proof.
