However occasionally the fix for a bug can not be implemented without ABI breakage, and it is decided that the fix warrants the impact of the ABI breakage. We have one of those situations coming along for RELENG_7 (what will become FreeBSD 7.1). The ABI breakage should only impact kernel modules that are not part of the baseline system (those will be patched by the MFC) which deal with advisory locks. As such the impact should not cause many people problems. The work that will be MFCed fixes issues with filesystem advisory locks, and moves the advisory locks list from filesystem-private data structures into the vnode structure. The MFC will be done by Kostantin Belousov some time this coming Friday (August 1st, 2008) if you have concerns and want to watch for it.
