Merge tag 'fixes_for_v6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack...

Pull UDF and ext2 fixes from Jan Kara:

 - Rewrite of udf directory iteration code to address multiple syzbot
   reports

 - Fixes to udf extent handling and block mapping code to address
   several syzbot reports and filesystem corruption issues uncovered by
   fsx & fsstress

 - Convert udf to kmap_local()

 - Add sanity checks when loading udf bitmaps

 - Drop old VARCONV support which I've never seen used and which was
   broken for quite some years without anybody noticing

 - Finish conversion of ext2 to kmap_local()

 - One fix to mpage_writepages() on which other udf fixes depend
