KDL in block notifier when using dd to create a file

[bga]

I am trying to figure out where our memory goes when running stuff and one of the tests I did was trying to exercise the cache to see if we were, for example, considering some memory that was actually cache memory as normal used memory (the good news is, it seems we are not). For that I used dd with the following parameters:

dd if=/dev/zero of=test.img bs=8192 count=393216

The command above can be seen in the screenshot you can also see the df output that showed the partition had 3.6 Gb free (and the dd command above would generate a 3 Gb file).
