From: Deepa Dinamani Date: Wed, 14 Mar 2018 04:03:27 +0000 (-0700) Subject: time: Introduce CONFIG_64BIT_TIME in architectures X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d4703ddafd1e05b8ec8f3fc8f4fbb4f88789a5ea;p=openwrt%2Fstaging%2Fblogic.git time: Introduce CONFIG_64BIT_TIME in architectures There are a total of 53 system calls (aside from ioctl) that pass a time_t or derived data structure as an argument, and in order to extend time_t to 64-bit, we have to replace them with new system calls and keep providing backwards compatibility. To avoid adding completely new and untested code for this purpose, we introduce a new CONFIG_64BIT_TIME symbol. Every architecture that supports new 64 bit time_t syscalls enables this config. After this is done for all architectures, the CONFIG_64BIT_TIME symbol will be deleted.
