[PATCH 34/35] fs-tests: integck: lessen memory consumption even more

[Artem Bityutskiy]

From: Artem Bityutskiy <Artem.Bityutskiy at nokia.com>

This patch kills the "name" field from 'struct file_info' where we stored
the original file name. We do not really need to keep this name around,
becaus it might have long gone and it is not very interesting. Besides,
we have several memory leaks where we leak 'file->name' strings, so this
is the easiest way to fix those leaks as well.
