Jeff Layton	6e8b50d16a	nfsd: add new io class tracepoint ... Add some new tracepoints in the nfsd read/write codepaths. The idea is that this will give us the ability to measure how long each phase of a read or write operation takes. Signed-off-by: Jeff Layton <jeff.layton@primarydata.com> Signed-off-by: J.

Jeff Layton	825213e59e	nfsd: move include of state.h from trace.c to trace.h ... Any file which includes trace.h will need to include state.h, even if they aren't using any state tracepoints. Ensure that we include any headers that might be needed in trace.h instead of relying on the *.c files to have the right ones.

Christoph Hellwig	31ef83dc05	nfsd: add trace events ... For now just a few simple events to trace the layout stateid lifetime, but these already were enough to find several bugs in the Linux client layout stateid handling. Signed-off-by: Christoph Hellwig <hch@lst.de>	2015-02-02 18:09:44 +01:00
