Subject: signal to kernel headers that time_t is 64-bit
X-Git-Tag: v1.2.0~54
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f12bd8e05c8bb2c3e2b91d635887ec424ef8fbd9;p=oweals%2Fmusl.git

signal to kernel headers that time_t is 64-bit

linux/input.h and perhaps others use this macro to determine whether
the userspace time_t is 64-bit when potentially defining types in
terms of time_t and derived structures. the name __USE_TIME_BITS64 is
unfortunate; it really should have been in the __UAPI namespace. but
this is what was chosen back in v4.16 when first preparing input.h for
time64 userspace, presumably based on expectations about what the
glibc-internal features.h macro for time64 would be, and changing it
now would just put a new minimum version requirement on kernel
headers.

the __USE_TIME_BITS64 macro is not intended as a public interface. it
is purely an internal contract between libc and Linux uapi headers.
