Hello Minchan,

Sorry for not replying sooner.

yes.


a) + __GFP_HIGHMEM in 2/3 and 3/3

b) can I add two small nitpicks from my side?

#1 s/could/can/ ?
-  * This function could be called in swapout/fs write path
-  * so we couldn't use GFP_FS|IO. And it assumes we already

+  "This function can be called in swapout/fs write path so we can't use"

#2 can you please add spaces around GFP flags? it's just a bit easier to read.

   GFP_NOIO | __GFP_HIGHMEM | __GFP_NORETRY | __GFP_NOWARN | __GFP_NOMEMALLOC
vs
   GFP_NOIO|__GFP_HIGHMEM|__GFP_NORETRY|__GFP_NOWARN|__GFP_NOMEMALLOC


c) Acked-by: Sergey Senozhatsky <sergey.senozhatsky@...il.com>

Thank you.
