pNFS/flexfiles: Fix the reset of struct pgio_header when resending

2015-06-26T19:39:50+00:00

hdr->good_bytes needs to be set to the length of the request, not zero. Cc: stable@vger.kernel.org # 4.0+ Signed-off-by: Trond Myklebust

pNFS/flexfiles: Turn off layoutcommit for servers that don't need it

2015-06-26T18:51:32+00:00

This patch ensures that we record the value of 'ffl_flags' from the layout, and then checks for the presence of the FF_FLAGS_NO_LAYOUTCOMMIT flag before deciding whether or not to call pnfs_set_layoutcommit(). The effect is that servers now can decide whether or not they want the client to call layoutcommit before returning a writeable layout. Signed-off-by: Trond Myklebust

pnfs/flexfiles: protect ktime manipulation with mirror lock

2015-06-26T18:01:37+00:00

It looks as if xchg() and cmpxchg() are not available for 64-bit integers on sparc32: > New breakage seen in linux-next today: > > ERROR: "__xchg_called_with_bad_pointer" [fs/nfs/flexfilelayout/nfs_layout_flexfiles.ko] undefined! > ERROR: "__cmpxchg_called_with_bad_pointer" [fs/nfs/flexfilelayout/nfs_layout_flexfiles.ko] undefined! > make[2]: *** [__modpost] Error 1 > make[1]: *** [modules] Error 2 Given that mirror ktime manipulation is already under mirror->lock, let's make use of the fact.

pnfs/flexfiles: add ff_layout_prepare_layoutstats

2015-06-24T14:53:11+00:00

It fills in the generic part of LAYOUTSTATS call. One thing to note is that we don't really track if IO is continuous or not. So just fake to use the completed bytes for it. Still missing flexfiles specific part, which will be included in the next patch. Reviewed-by: Jeff Layton Signed-off-by: Peng Tao Signed-off-by: Trond Myklebust
