A problem with respect to data read through the buffer cache for both
NFS clients was reported to freebsd-fs@ under the subject "NFS
corruption in recent HEAD" on Nov. 26, 2011. This problem occurred when
a TCP mounted root fs was changed to using UDP. I believe that this
problem was caused by the change in mnt_stat.f_iosize that occurred
because rsize was decreased to the maximum supported by UDP. This
patch fixes the problem by using v_bufobj.bo_bsize instead of f_iosize,
since the latter is set to f_iosize when the vnode is allocated, but
does not change for a given vnode when f_iosize changes.
__COUNTER__ allows one to obtain incrementing (read: unique) numbers
from the C preprocesor. This is useful when implementing things like a
robust implementation of CTASSERT(), which currently fails when using
it more than once on a single line of code. Probably not likely to cause
any breakage, but still.
__COUNTER__ was also added to GCC 4.3, but since that implementation is
GPLv3 licensed, I took the liberty of implementing it without looking at
any upstream sources. Therefore, this version is licensed under the same
license as the rest of the code; GPLv2.
In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.
