Pull up following revision(s), all via patch,
requested by reinoud in ticket #1432:
sys/fs/udf/udf_vfsops.c: revision 1.83
sys/fs/udf/udf_allocation.c: revision 1.45
sys/fs/udf/udf_subr.c: revision 1.160
sys/fs/udf/udf_subr.c: revision 1.161
While searching the VAT on recordable media, search the last sector too!
This fixes Win10 formatted discs from being mounted incorrectly.
Make sysctl udf.verbose dependent on UDF_DEBUG instead of DEBUG
Fix serious issue with recordable media formatted with Win10. When closing it
after modification the VAT was written out corrupted making the disc
unreadable anymore on remount. Thanks for ig@ for spotting it in the wild!
On freeing a virtual address in the VAT, use the correct value; this might
confuse other implementations who can reject the VAT on this.
