From 17f859d3c409bf2730a47d56979c0700171006b7 Mon Sep 17 00:00:00 2001 From: Jakob Unterwurzacher Date: Sun, 6 Jun 2021 19:22:16 +0200 Subject: fusefronted: report plaintext size on symlink creation gocryptfs 2.0 introduced the regression that the size reported at symlink creation was the ciphertext size, which is wrong. Report the plaintext size.
