ANDROID: fscrypt: add key removal notifier chain Add a notifier chain so that sdcardfs can evict its dentries when an fscrypt key is about to be removed. This is needed for the FS_IOC_REMOVE_ENCRYPTION_KEY ioctl to properly "lock" the encrypted files underneath sdcardfs when an Android user is stopped. This is meant to be a temporary patch carried as part of the sdcardfs patchset until either we stop using sdcardfs, we get sdcardfs upstream, or we find a way to provide what sdcardfs needs while also benefitting a user upstream.
