  "message": "[PATCH] NFS: Introduce the use of inode-\u003ei_lock to protect fields in nfsi\n\nDown the road we want to eliminate the use of the global kernel lock entirely\nfrom the NFS client.  To do this, we need to protect the fields in the\nnfs_inode structure adequately.  Start by serializing updates to the\n\"cache_validity\" field.\n\nNote this change addresses an SMP hang found by njw@osdl.org, where processes\ndeadlock because nfs_end_data_update and nfs_revalidate_mapping update the\n\"cache_validity\" field without proper serialization.\n\nTest plan:\n Millions of fsx ops on SMP clients.  Run Nick Wilson\u0027s breaknfs program on\n large SMP clients.\n\nSigned-off-by: Chuck Lever \u003ccel@netapp.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
