Pull nilfs2 updates from Viacheslav Dubeyko:

 - Fix potential block overflow that cause system hang

   When executing the FITRIM command, an underflow can occur in the
   calculation of nblocks. This ultimately leads to the block layer
   function __blkdev_issue_discard() taking an excessively long time
   to process the bio chain, and the ns_segctor_sem lock remains held
   for a long period.

   This prevents other tasks from acquiring the ns_segctor_sem lock,
   resulting in a hang reported by syzbot (Edward Adam Davis)

 - Fix missing struct keywords in nilfs2_api.h kernel-doc (Ryusuke
   Konishi)

 - Convert nilfs_super_block to kernel-doc

   Eliminate 40+ kernel-doc warnings in nilfs2_ondisk.h by converting
   all of the struct member comments to kernel-doc comments (Randy
   Dunlap)
