Subject: MIPS: Setup errno for {f,l,}xstat
X-Git-Tag: glibc-2.35~535
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=66016ec8aeefd40e016d7040d966484c764b0e9c;p=thirdparty%2Fglibc.git

MIPS: Setup errno for {f,l,}xstat

{f,l,}xstat stub for MIPS is using INTERNAL_SYSCALL
to do xstat syscall for glibc ver, However it leaves
errno untouched and thus giving bad errno output.

Setup errno properly when syscall returns non-zero.
