# Update sysdeps/unix/sysv/linux/syscall-names.list with additional
# names found in the generated <arch-syscall.h> file, so that the
# global system call names list is a superset of the
# architecture-specific system call names.

# configured, but not-yet-built glibc tree.
#
# --lock points to a file not replaced during the update operation, so
