We will hit the BUG_ON\nwhen we write the last block (2^32-1) into the sparse file.\n\nThe root cause of the problem lies in the fact that we specifically set\ns_maxbytes so that block at s_maxbytes fit into on-disk extent format,\nwhich is 32 bit long. However, we are not storing start and end block\nnumber, but rather start block number and length in blocks. It means\nthat in order to cover extent from 0 to EXT_MAX_BLOCK we need\nEXT_MAX_BLOCK+1 to fit into len (because we counting block 0 as well) -\nand it does not.\n\nThe only way to fix it without changing the meaning of the struct\next4_extent members is, as Kazuya Mio suggested, to lower s_maxbytes\nby one fs block so we can cover the whole extent we can get by the\non-disk extent format.\n\nAlso in many places EXT_MAX_BLOCK is used as length instead of maximum\nlogical block number as the name suggests, it is all a bit messy.
