btrfs: use struct fscrypt_str instead of struct qstr
Browse files Browse the repository at this point in the history 
[ Upstream commit 6db7531 ]

While struct qstr is more natural without fscrypt, since it's provided
by dentries, struct fscrypt_str is provided by the fscrypt handlers
processing dentries, and is thus more natural in the fscrypt world.
Replace all of the struct qstr uses with struct fscrypt_str.
