Subject: [PATCH] mount: remove redundant panic() in mnt_init()
Date: Mon, 20 Jul 2026 07:23:31 -0400	[thread overview]
Message-ID: <20260720112331.1096530-1-hamzamahfooz@linux.microsoft.com> (raw)

Since at least as far back as commit 0818bf27c05b ("resizable
namespace.c hashes"), we call alloc_large_system_hash() in
mnt_init() which already panics if the table is NULL.
