From a6d5eedb9ed112474ab1988013fc812bc6056c7a Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Tue, 9 Jul 2019 12:22:30 +0200 Subject: mkfs.ubifs: remove ZSTD_CLEVEL_DEFAULT for backwards compatibillity Support for ZSTD compression has been added recently through the ZSTD library, which is famously known for its incredibly well designed and stable API. This patch removes usage of ZSTD_CLEVEL_DEFAULT, which isn't exposed in older versions of the ZSTD library, and replaces it with with the constant parameter 0. According to the documentation this should then use a reasonable default (which is defined internally). Other possible approachs include defining ZSTD_CLEVEL_DEFAULT to 3 (the value it _currently_ has) if it isn't defined. This patch chooses the approach of passing 0 since this seems to be encouraged by the existing documentation.
