> When a 32-bit program that was not compiled with large file offsets does a
> stat and gets a st_ino value back that won't fit in the 32 bit field, glibc
> (correctly) generates an EOVERFLOW error. We can't do anything about fs's
> with larger permanent inode numbers, but when we generate them on the fly,
> we ought to try and have them fit within a 32 bit field.

> This patch takes the first step toward this by making the static counters in
> these two functions be 32 bits.
