Revision 3d4b2fcbc980879a1385d5d7d17a4ffd0ee9aa1f authored by Eric Biggers on 19 December 2016, 19:15:48 UTC, committed by Richard Weinberger on 17 January 2017, 13:34:21 UTC
In several places, ubifs checked for an encryption key before creating a file in an encrypted directory. This was redundant with fscrypt_setup_filename() or ubifs_new_inode(), and in the case of ubifs_link() it broke linking to special files. So remove the extra checks.
