Subject: fscrypt: Drop FORBID_WEAK_KEYS flag for AES-ECB
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=53d9218d8d38cd33e065cc46db996608adec6687;p=users%2Fjedix%2Flinux-maple.git

fscrypt: Drop FORBID_WEAK_KEYS flag for AES-ECB

This flag only has an effect for DES, 3DES, and XTS mode.  It does
nothing for AES-ECB, as there is no concept of weak keys for AES.
