SubjectRe: [PATCH] fdset's leakage
[strange loop snipped]

That other fix looks buggy btw. Here it is:

- nfds = 8 * L1_CACHE_BYTES;
- /* Expand to the max in easy steps */
- while (nfds <= nr) {
- nfds = nfds * 2;
- if (nfds > NR_OPEN)
- nfds = NR_OPEN;
- }
+ nfds = max_t(int, 8 * L1_CACHE_BYTES, roundup_pow_of_two(nfds));
+ if (nfds > NR_OPEN)
+ nfds = NR_OPEN;

Surely you meant to say "roundup_pow_of_two(nr + 1)"?
