* [PATCH 0/6] Transition vfs to 64-bit timestamps @ 2018-05-12 4:59 Deepa Dinamani 2018-05-12 4:59 ` [PATCH 3/6] ceph: make inode time prints to be long long Deepa Dinamani 0 siblings, 1 reply; 2+ messages in thread From: Deepa Dinamani @ 2018-05-12 4:59 UTC (permalink / raw) To: viro, tglx Cc: arnd, linux-kernel, linux-fsdevel, y2038, andreas.dilger, anton, balbi, bfields, ceph-devel, darrick.wong, dhowells, dsterba, dwmw2, hch, hirofumi, hubcap, jack, jaegeuk, jaharkes, jslaby, keescook, mark, miklos, nico, reiserfs-devel, richard, sage, sfrench, swhiteho, tj, trond.myklebust, tytso, zyan The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. I've tried to keep the conversions with the script simple, to aid in the reviews. I've kept all the internal filesystem data structures and function signatures the same. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions.
