Why glibc's fstat() is slow

You're not taking all the possible future needs for extensions into account.

We really should standardize on names like: fstat_new$_2006revB.2_2023revA()

Just increment dates and revisions every time you propose a patch, and document the history by keeping track of precursors of the updated API.

I'm torn between this proposal and adding full Git hashes to all symbols...
