Subject: [dpdk-dev] [PATCH] memory: fix alignment in eal_get_virtual_area()
Date: Wed, 13 Jun 2018 21:08:14 +0200	[thread overview]
Message-ID: <1528916894-1991-1-git-send-email-dariuszx.stojaczyk@intel.com> (raw)

Although the alignment mechanism works as intended, the
`no_align` bool flag was set incorrectly. We were aligning
buffers that didn't need extra alignment, and weren't
aligning ones that really needed it.

Fixes: b7cc54187ea4 ("mem: move virtual area function in common directory")
