Symlinks cannot have ACLs, so set_acl should either never be defined for symlinks (and a NULL check is then needed in posix_acl_xattr_set()), or it is defined in all inode operations, and S_ISNLNK() check is needed in posix_acl_xattr_set(). That latter check should probably be added in any case to be on the safe side. Yes, we should add the check. We also in general should not have set_acl/get_acl on links and I'll look over it. > Patch 6 also declares posix_acl_prepare() but this function is never introduced; this must be a leftover from a previous version. Indeed.
