[PATCH 0/2 v8] XFS TESTS: ENOSPC Punch Hole Test

[Allison Henderson <achender@linux.vnet.ibm.com>]

This patch set adds the ENOSPC test that was used for ext4 punch hole testing.
This test will verify that a hole can be punched even when the disk is full.
Reserved blocks should be used to complete the operation when there is not blocks
to further fragment the file.

Because punching a hole does not always require extra blocks, there needs to 
be several iterations of punching holes, and then filling the file system to 100% 
usage before it is forced to grow the tree in order to handle the fragmentation. 
The growing of the tree is what would cause ENOSPC if not for the use of reserved blocks.
