package/lttng-babeltrace/0001-no-posix-fallocate-in-uclibc.patch

   1 Do not call posix_fallocate() on uClibc
   2
   3 uClibc does not implement posix_fallocate(), and posix_fallocate() is
   4 mostly only an hint to the kernel that we will need such or such
   5 amount of space inside a file. So we just don't call posix_fallocate()
   6 when building against uClibc.
