This is a series of cleanups for the y2038 work, mostly intended for namespace cleaning: the kernel defines the traditional time_t, timeval and timespec types that often lead to y2038-unsafe code. Even though the unsafe usage is mostly gone from the kernel, having the types and associated functions around means that we can still grow new users, and that we may be missing conversions to safe types that actually matter.
As there is no rush on any of these patches, I would either queue them up in linux-next through my y2038 branch, or Thomas could add them to the tip tree if he wants.
As mentioned in another series, this is part of a larger effort to fix all the remaining bits and pieces that are not completed yet from the y2038 conversion, and the full set can be found at:
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y...
Maintainers, please review and provide Acks.
Let me know if you have any opinion on whether we should do the include last two patches of this series or not.
ArndArnd Bergmann (23): y2038: remove CONFIG_64BIT_TIME y2038: add __kernel_old_timespec and __kernel_old_time_t y2038: vdso: change timeval to __kernel_old_timeval y2038: vdso: change timespec to __kernel_old_timespec y2038: vdso: change time_t to __kernel_old_time_t y2038: vdso: nds32: open-code timespec_add_ns() y2038: vdso: powerpc: avoid timespec references y2038: ipc: remove __kernel_time_t reference from headers y2038: stat: avoid 'time_t' in 'struct stat' y2038: uapi: change __kernel_time_t to __kernel_old_time_t y2038: rusage: use __kernel_old_timeval y2038: syscalls: change remaining timeval to __kernel_old_timeval y2038: socket: remove timespec reference in timestamping y2038: make ns_to_compat_timeval use __kernel_old_timeval y2038: elfcore: Use __kernel_old_timeval for process times y2038: timerfd: Use timespec64 internally y2038: time: avoid timespec usage in settimeofday() y2038: itimer: compat handling to itimer.c y2038: use compat_{get,set}_itimer on alpha y2038: move itimer reset into itimer.c y2038: itimer: change implementation to timespec64 [RFC] y2038: itimer: use ktime_t internally y2038: allow disabling time32 system calls
I've dropped the "[RFC] y2038: itimer: use ktime_t internally" patch for the moment, and added two other patches from other series:
y2038: remove CONFIG_64BIT_TIME y2038: socket: use __kernel_old_timespec instead of timespec
Tentatively pushed out the patches with the Acks I have received so far to my y2038 branch on git.kernel.org so it gets included in linux-next.
If I hear no complaints, I'll send a pull request for the merge window, along with the compat-ioctl series I have already queued up in the same branch.
