Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/ufs/ext2fs: ext2fs_inode.c
        src/sys/ufs/ffs: ffs_inode.c
        src/sys/ufs/lfs: lfs_inode.c
        src/sys/ufs/ufs: ufs_inode.c

Log Message:
- ufs_balloc_range(): on error, only PG_RELEASED the pages that were
  allocated to extend the file to the new size. Releasing all pages
  may release pages that contains previously-written data not yet flushed
  to disk. Should fix PR kern/35704
- {ffs,lfs,ext2fs}_truncate(): Even if the inode's size is the same as
  the new length, call uvm_vnp_setsize(). *_truncate() may have been
  called by *_write() in the error path (e.g. block allocation failure
  because of quota of file system full), and at this point v_writesize
  has been set to the desired size of the file and not reverted to the
  old size. Not adjusting v_writesize to the real size cause
  genfs_do_io() to write to disk past the real end of the file.
