But that means your glibc supports it. Then we don't need the syscall at
all.
To me it's only present in the kernel headers (linux-libc-dev) like this:
[pb64: ~]# grep -r syncfs /usr/include
/usr/include/asm/unistd_64.h:#define __NR_syncfs
306
/usr/include/asm/unistd_64.h:__SYSCALL(__NR_syncfs, sys_syncfs)
/usr/include/asm/unistd_32.h:#define __NR_syncfs 344
/usr/include/asm-generic/unistd.h:#define __NR_syncfs 267
/usr/include/asm-generic/unistd.h:__SYSCALL(__NR_syncfs, sys_syncfs)
Greets,
Stefan
