Subject: [PATCH 0/2] Fix compound_head() race
Date: Thu, 13 Aug 2015 18:54:44 +0300 [thread overview]
Message-ID: <1439481286-81093-1-git-send-email-kirill.shutemov@linux.intel.com> (raw)
Here's my attempt on fixing recently discovered race in compound_head().
It should make compound_head() reliable in all contexts.
The patchset is against Linus' tree. Let me know if it need to be rebased
onto different baseline.
It's expected to have conflicts with my page-flags patchset and probably
should be applied before it.

zsmalloc: use page->private instead of page->first_page
