mmapwrite spawns several threads, all of which perform writes on a file for the purpose of testing the behavior of mmap(2)-ed files. One thread performs an mmap and a write to the beginning of that region, while the others perform regular writes after lseek(2)-ing the end of the file. Because these regular writes are set in a while (1) loop, they will write an unbounded amount of data to disk. The mmap_write_001_pos test script SIGKILLs them after 30 seconds, but on fast testbeds, this may be enough time to exhaust the available space in the filesystem, leading to spurious test failures. Instead, limit the total file size by checking that the lseek return value is no greater than 250 * 1024*1024 bytes, which is less than the default minimum vdev size defined in includes/default.cfg .
