Subject: [PATCH v2 11/12] smb/client: check if SMB1 DOS/SRV error mapping arrays are sorted
Date: Wed, 1 Apr 2026 07:29:11 +0000 [thread overview]
Message-ID: <20260401072912.355072-12-huiwen.he@linux.dev> (raw)
In-Reply-To: <20260401072912.355072-1-huiwen.he@linux.dev>
From: Youling Tang <tangyouling@kylinos.cn>
Although the arrays are sorted at build time, verify the ordering again
when cifs.ko is loaded to avoid potential regressions introduced by
future script changes.
