Where in the ext2/3 code does it know that a block on the disk is now
free to reuse?
Thanks,

Hi Chris,
File systems track which blocks are free from the file system creation
time (mkfs), creation of new files and deletion. Ext2/3 is the
gatekeeper for all deletions, so it knows when file system blocks
transition from the used state to the free state. Ext file system use
bitmaps to track the blocks that are allocated or not.
Regards,
Ric
