On 32bit arm systems, starting with glibc 2.33, the fstatat64 syscall is used to fix a y2038 bug and statx is also called for 64bit->32bit datastructure conversion. See this upstream glibc 2.33 commit range for more details: d892723830..aa03f722f3. Example failures (only on 32bit arm): type=SECCOMP comm="mtpd" exe="/usr/sbin/mtpd" sig=0 arch=40000028 syscall=327 code=0x7ffc0000 type=SECCOMP comm="mtpd" exe="/usr/sbin/mtpd" sig=0 arch=40000028 syscall=397 code=0x7ffc0000 BUG=b:187795855 TEST=Local builds; CQ.
