This is because fscrypt wants to set d_revalidate only on some dentries, so it does it only for them in d_revalidate. But, case-insensitive hooks are actually set on all dentries in the filesystem, so the natural place to do it is through s_d_op and let d_alloc handle it [1]. In addition, doing it inside the ->lookup is a problem for case-insensitive dentries that are not created through ->lookup, like those coming open-by-fhandle[2], which will not see the required d_ops. This patchset therefore reverts to using sb->s_d_op to set the dentry operations for case-insensitive filesystems. In order to set case-insensitive hooks early and not require every dentry to have d_revalidate in case-insensitive filesystems, it introduces a patch suggested by Al Viro to disable d_revalidate on some dentries on the fly. It survives fstests encrypt and quick groups without regressions. Based on v6.7-rc1.
