Merge tag 'fscrypt_for_linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt
Pull fscrypt updates from Ted Ts'o: "Clean up fscrypt's dcache revalidation support, and other miscellaneous cleanups" * tag 'fscrypt_for_linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: fscrypt: cache decrypted symlink target in ->i_link vfs: use READ_ONCE() to access ->i_link fscrypt: fix race where ->lookup() marks plaintext dentry as ciphertext fscrypt: only set dentry_operations on ciphertext dentries fs, fscrypt: clear DCACHE_ENCRYPTED_NAME when unaliasing directory fscrypt: fix race allowing rename() and link() of ciphertext dentries fscrypt: clean up and improve dentry revalidation fscrypt: use READ_ONCE() to access ->i_crypt_info fscrypt: remove WARN_ON_ONCE() when decryption fails fscrypt: drop inode argument from fscrypt_get_ctx()
