Ext3 users - Apr 2009 - E2fsck and large file

How big is a file that e2fsck considers it to be a large file?

  814611 blocks used (42.79%)
       0 bad blocks
       1 large file <----- that


Thanks

        if (LINUX_S_ISREG(inode->i_mode) &&
            (inode->i_size_high || inode->i_size & 0x80000000UL))
                ctx->large_files++;

2G or greater.

2GB.  This is the size at which point the LARGEFILE read-only compat
flag is set.  It's there so that really old kernels (pre Linux version
2.4) don't try to modify, and thus corrupt filesystems that have > 2GB
files, since Linux 2.2 kernels didn't support files larger than 2
gigabytes.

It's largely a historical issue in this day and age, but it does have
a very specific meaning.
