Subject:     syscall: remove calls to Entersyscall & Exitsyscall in Getdents
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=378ef472dfc0937d69441973eeccc96a5dc3699c;p=thirdparty%2Fgcc.git

syscall: remove calls to Entersyscall & Exitsyscall in Getdents

    The syscall for Getdents in syscall/libcall_linux.go
    called Entersyscall and Exitsyscall, causing the
    runtime_sched counts for goroutines to be incorrect.
    Inconsistent counts caused checkdead in runtime/proc.c
    to panic.

    Fixes golang/go#11406
