To: linux-ext4@...r.kernel.org
Cc: adilger.kernel@...ger.ca
Subject: [PATCH v3 5/7] ext2fs: add EXT4_FEATURE_INCOMPAT_64INODE support
Inodes count and free inodes count should be 64 bit long.
This patch also changes s_inodes_count* to 64 bit
Lustre-bug: https://jira.hpdd.intel.com/browse/LU-9309
Signed-off-by: Artem Blagodarenko <artem.blagodarenko@...il.com>
