| |
3.16.50-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fainelli <f.fainelli@gmail.com>
commit 7d6d067790289e4f61f59fa60550ca5918aa25bd upstream.
On 32-bit hosts and with CONFIG_DEBUG_LOCK_ALLOC we should be seeing a lockdep splat indicating this seqcount is not correctly initialized, fix that.
