Subject: package/mke2img: set sparse_super for revision 1
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=225189803d9ecb07aef3f7f016376c7eb00dc44d;p=buildroot.git

package/mke2img: set sparse_super for revision 1

The sparse_super feature is more efficient in terms of speed and
available space, so set it by default if supported, i.e. for revision 1.

This gives a huge speed gain for large resize2fs operations, especially
for expansion.
