[PATCH 4/9] xfs: make GFP_ usage consistent when allocating buftargs

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Convert kmem_zalloc to kzalloc, and make it so that both memory
allocation functions in this function use GFP_NOFS.
