Ts'o" Cc: linux-fsdevel@vger.kernel.org, linux-ext4@vger.kernel.org, linux-mtd@lists.infradead.org, Eric Biggers , linux-f2fs-devel@lists.sourceforge.net From: Eric Biggers Filesystems only ever access 'struct fscrypt_ctx' through fscrypt functions. But when a filesystem is built without encryption support, these functions are all stubbed out, so the declaration of fscrypt_ctx is unneeded. Therefore, move it from fscrypt.h to fscrypt_supp.h.
