From f540faf72d815816e9d50397ddad467365b3940f Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Tue, 22 Jan 2013 08:07:06 -0500 Subject: [PATCH 14/14] lnfs: Do not sleep holding the inode spin lock. The nfs_setsecurity code can sleep while allocating memory so the inode spin lock can not be held while during this call.
