The patch titled Subject: nilfs2: use 64-bit superblock timstamps has been added to the -mm tree. Its filename is nilfs2-use-64-bit-superblock-timstamps.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/nilfs2-use-64-bit-superblock-timstamps.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/nilfs2-use-64-bit-superblock-timstamps.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: nilfs2: use 64-bit superblock timstamps The mount time field in the superblock uses a 64-bit timestamp, but calling get_seconds() may truncate the current time to 32 bits. This changes it to ktime_get_real_seconds() to avoid the potential overflow.
