Thomas Schoebel-Theuer e7464b3c02 all: correct error code EIO 
The error code -EIO should always refer to a problem of
lower storage laysers. Thus MARS should not generate that
code itself, but other ones.

Thomas Schoebel-Theuer 99644a943a all: make *_switch() code idempotent 
New semantics: it must be possible to call the switch functions
even when nothing has changed.

Daniel Hermann 83b658467b sio: fix call to vfs_fsync() for newest rhel6 kernels 
the number of arguments to vfs_fsync has changed in kernel 2.6.35.
The S_BIAS macro (removed at about the same time in 2.6.35) is used to
detect whether vfs_fsync must be called with 2 or 3 args. In RHEL6
kernels 2.6.32, the removal of S_BIAS was backported, but the change
in vfs_fsync was not. So a check for RHEL_MAJOR < 7 is used in
addition to S_BIAS to find the correct number of args for vfs_fsync
call.
