2.6.29-stable review patch. If anyone has any objections, please let us know. ------------------ From: Dan Williams commit 7a3ab908948b6296ee7e81d42f7c176361c51975 upstream. In the unlikely event that reshape progresses past the current request while it is waiting for a stripe we need to schedule() before retrying for 2 reasons: 1/ Prevent list corruption from duplicated list_add() calls without intervening list_del(). 2/ Give the reshape code a chance to make some progress to resolve the conflict.
