From d26978dd866dbb3b3a9690f3655a5e735055de89 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Thu, 17 Jan 2013 13:11:29 -0500 Subject: [PATCH] xfs: pull up stack_switch check into xfs_bmapi_write The stack_switch check currently occurs in __xfs_bmapi_allocate, which means the stack switch only occurs when xfs_bmapi_allocate() is called in a loop. Pull the check up before the loop in xfs_bmapi_write() such that the first iteration of the loop has consistent behavior.
