Subject: [PATCH RESEND] ecryptfs: Remove redundant if checks in encrypt_and_encode_filename
Date: Mon,  9 Mar 2026 23:48:24 +0100	[thread overview]
Message-ID: <20260309224824.85471-3-thorsten.blum@linux.dev> (raw)

The outer if already checks if 'mount_crypt_stat' is true. Drop checking
'mount_crypt_stat' again.  Use ecryptfs_printk() while we're at it.
