From e0f3ff7aa540fa0834e8adca08ddc3389fd85d4a Mon Sep 17 00:00:00 2001 From: Sungjong Seo Date: Tue, 24 May 2022 10:29:11 +0900 Subject: [PATCH] f2fs: allow compression for mmap files in compress_mode=user [ Upstream commit 66d34fcbbe63ebd8584b792e0d741f6648100894 ] Since commit e3c548323d32 ("f2fs: let's allow compression for mmap files"), it has been allowed to compress mmap files. However, in compress_mode=user, it is not allowed yet. To keep the same concept in both compress_modes, f2fs_ioc_(de)compress_file() should also allow it. Let's remove checking mmap files in f2fs_ioc_(de)compress_file() so that the compression for mmap files is also allowed in compress_mode=user.
