Subject: [PATCH 68/81] linux: Fix fstatat on MIPSn64 (BZ #29730)
|
||
|
||
Commit 6e8a0aac2f883 ("time: Fix overflow itimer tests on 32-bit
|
||
systems") changed in_time_t_range to assume a 32-bit time_t. This broke
|
||
fstatat on MIPSn64 that was using it with a 64-bit time_t due to
|
||
difference between stat and stat64. This commit fix that by adding a
|
||
MIPSn64 specific version, which bypasses the EOVERFLOW tests.
|
||
|
||
Resolves: BZ #29730
