Subject: [PATCH] kdb: remove redundant memset in kdb_initbptab()
Date: Sat, 24 Oct 2026 01:14:14 +0900 [thread overview]
Message-ID: <20261023161415.61051-1-ekffu200098@gmail.com> (raw)
kdb_breakpoints is zero-initialized and not used until kdb_initbptab(),
which only runs once during boot. So the memset in kdb_initbptab() has
no effect.
So remove the memset.
No functional change.
