From c61404153eb683da9c35aad133131554861ed561 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 25 May 2021 11:39:35 -0700 Subject: f2fs: introduce FI_COMPRESS_RELEASED instead of using IMMUTABLE bit Once we release compressed blocks, we used to set IMMUTABLE bit. But it turned out it disallows every fs operations which we don't need for compression. Let's just prevent writing data only.
