Subject: [PATCH 0/2] ipath/qib deadlock
Date: Fri, 04 Oct 2013 09:28:10 -0400 [thread overview]
Message-ID: <20131004132754.29116.76211.stgit@phlsvslse11.ph.intel.com> (raw)
These two patches fix flaws that have been
observed in the with qib.
The issue has also been code inspected by
Jan Kara in his get_user_pages_unlocked()
patch series.
By using get_user_pages_fast() the dependency
on Jan's patch set has been removed. I can't
find any issue with losing the force in these
use cases.
Jan Kara (2):
IB/ipath: Convert ipath_user_sdma_pin_pages() to use get_user_pages_fast()
IB/qib: Convert qib_user_sdma_pin_pages() to use get_user_pages_fast()
