[PATCH] fs: crypto: add CONFIG_BLOCK dependency
From: arnd@arndb.de (Arnd Bergmann)
Date: 2016-02-22 21:51:13
Also in:
linux-fsdevel, lkml
Subsystem:
filesystems (vfs and infrastructure), fscrypt: file system level encryption support, the rest · Maintainers:
Alexander Viro, Christian Brauner, Eric Biggers, Theodore Y. Ts'o, Jaegeuk Kim, Linus Torvalds
The newly added generic crypto abstraction for file systems operates
on 'struct bio' objects, which do not exist when CONFIG_BLOCK is
disabled:
fs/crypto/crypto.c: In function 'fscrypt_zeroout_range':
fs/crypto/crypto.c:308:9: error: implicit declaration of function 'bio_alloc' [-Werror=implicit-function-declaration]
This adds a Kconfig dependency that prevents FS_ENCRYPTION from being
enabled without BLOCK.
