[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gunthorpe <jgg@xxxxxxxxxx>

[ Upstream commit b0a6c883bcd42eeb0850135e529b34b64d57673c ]

Domain allocation is always done under a sleepable context, the v1 path
and other drivers use GFP_KERNEL already. Fix the v2 path to also use
GFP_KERNEL.
