From e4af440aaf390ac1d39b26ef6cf4a28bcb6a5979 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 5 Feb 2015 17:05:08 -0500 Subject: [PATCH] NFSv4.1: pnfs_send_layoutreturn should use GFP_NOFS In we want to be able to call pnfs_send_layoutreturn() from within the writeback path, we really want it to use GFP_NOFS in order to prevent recursion.
