Subject: [PATCH v3 4/7] libfs: Chain encryption checks after case-insensitive revalidation

From: Gabriel Krisman Bertazi <[email protected]>

Support encrypted dentries in generic_ci_d_revalidate by chaining
fscrypt_d_revalidate at the tail of the d_revalidate. This allows
filesystem to just call generic_ci_d_revalidate and let it handle any
case-insensitive dentry (encrypted or not).

Signed-off-by: Gabriel Krisman Bertazi <[email protected]>

Changes since v2:
- Enable negative dentries of encrypted filesystems (Eric)
