From 57d5f64d83ab5b5a5118b1597386dd76eaf4340d Mon Sep 17 00:00:00 2001 From: Parthasarathy Bhuvaragan Date: Fri, 13 Jan 2017 15:46:25 +0100 Subject: tipc: allocate user memory with GFP_KERNEL flag Until now, we allocate memory always with GFP_ATOMIC flag. When the system is under memory pressure and a user tries to send, the send fails due to low memory. However, the user application can wait for free memory if we allocate it using GFP_KERNEL flag. In this commit, we use allocate memory with GFP_KERNEL for all user allocation. Reported-by: Rune Torgersen Acked-by: Jon Maloy Signed-off-by: Parthasarathy Bhuvaragan Signed-off-by: David S.
