>From ecb696160da6b38288ca7a339c2c386bf4955fba Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Mon, 29 Feb 2016 09:00:36 -0500 Subject: [PATCH 1/2] xfstests: move generic indlen reservation test to xfs dir This test was originally designed to reproduce the split indlen reservation depletion problem in XFS. It was included as a generic test simply because it had no hard dependencies on XFS or associated tools. This test is no longer effective in its current form. Fixing it requires use of XFS specific mechanisms. Therefore, move the test to the XFS specific test directory. No other changes are made in this patch.
