| |
See that we finally got a larger dev_t. Very good! Will check over time what form my patches got in the current tree. The first one I checked was broken a little. Below a fix.
[ext2 used a 32-bit field for dev_t, with possibly undefined storage following; thus, no action was required to go to 32-bit dev_t, but going to 64-bit dev_t required some subtlety: 0 was written in the first word and the 64 bits in the following two. Al truncated my 64-bit stuff to 32 bits but did not understand why there was this split, and wrote 0 followed by a single word. We should at least zero the word following to have well-defined storage later.]
