Sounds like it, Josh posted this output before:

[  516.859103] imap_blocks 7 zmap_blocks 7 firstdatazone c11
log_zone_size 0 max_size 7fffffff magic 4d5a nzones 3001c blocksize:
1000

So there are 7 blocks in the zone bitmap but only 0x3001c - 0xc11 = 193547
zones to allocate, which would fit in 6 blocks.
