Hi Ken,

I'm having some trouble understanding your reproduction steps.  This is inside
an LTFS mount?

1. You read 1GB of /dev/zero in 1MB chunks and write it to foo;
2. ls -l foo reports the expected 1GB size;
3. reading foo with a 1MB request size returns 64k, and unexpected end of file.

I'm really curious how this change breaks LTFS, given a 4k iosize "works."

Thanks!
