pnfs/flexfiles: protect ktime manipulation with mirror lock
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.
