<pre wrap="">The testing script based on tao's testcase for inode allocation performance test.
It helps to run a performance comparison tests between a original and patched kernel
on inode allocation, deletion and traversing etc. which automates the testing procedures
of patch applying,kernel rebuilding etc, and also calculate a human-readable testing report
by the end.
