Changed rename(2) to do nothing if its args resolve to the same existing file, as seems to be required by POSIX. MFC: ext2fs_vnops.c 1.69, ufs_vnops.c 1.205: Replaced the resulting dead dead code by a check that it is not reached. PR: 42617

si_iosize_max correctly in ffs, and don't forget to set it in cd9660 and ext2fs (the original log message mistakenly said msdosfs instead of cd9660)).

Bump __FreeBSD_version to 440002 to account for the mount structure

change (LIST vnodelist -> TAILQ nvnodelist). At this time I am also adding a second TAILQ list, currently reserved, to the mount structure that will later be used to split the vnode list into a clean and dirty list, so as to get all mount structure changes over and done with now.

MFC change vnode list under mount point from LIST to TAILQ in preparation

MFC: Change the interface to vflush() so that it can deal with

extra references on the filesystem root vnode. This fixes bugs in a number of filesystems that could cause forced umounts to erroneously return EBUSY, and it centralises a lot of xxx_unmount logic. This unfortunately requires the recompilation of any filesystem KLDs, although I have added an extra sanity check that should help to avoid panics if old modules are used (the filesystem may refuse to umount, and if so, a warning message will appear on the console). Not objected to by: -stable

Convert all users of fldoff() to offsetof(). fldoff() is bad because it only takes a struct tag which makes it impossible to use unions, typedefs etc. Define __offsetof() in Define offsetof() in terms of __offsetof() in and
