+Subject: [PATCH] mkfs.f2fs: fix missing cpu_to_le64 for checkpoint version
+
+The error on mips was reported by Stijn as follow.
+
+Commit 8399a29df92d6867d226df362edbf2e0efa527c1 in f2fs-tools
+("mkfs.f2fs: give random checkpoint version") causes a bug when mounting
+a filesystem created with it on a MIPS64 device running a 4.4(.83)
+kernel. The following kernel warning appears several times per second,
+for 30 seconds:
