[patch] xHCI: use gfp flags from caller instead of GFP_ATOMIC

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

 



We're not holding a lock here so we can use the gfp flags the caller
specifies instead of GFP_ATOMIC.  The callers use GFP_ATOMIC so this
change doesn't affect how the kernel runs, but it's a cleanup.
