Subject: [edk2-platforms][PATCH v2 02/11] Ext4Pkg: Move EXT4_NAME_MAX definition to Ext4Disk.h
Date: Mon, 12 Dec 2022 20:46:45 +0600 [thread overview]
Message-ID: <20221212144654.2650-3-savvamtr@gmail.com> (raw)
In-Reply-To: <20221212144654.2650-1-savvamtr@gmail.com>
Constant EXT4_NAME_MAX is related to EXT4_DIR_ENTRY FS structure, so it
should be placed into Ext4Disk.h header
