Hi,

Patch 1 just adds support for fdinfo outputting state of the locked
poll hash table, something which was forgotten when that support was
added earlier.

Patch 2 fixes a race where multiple requests on the same poll waitqueue
may get woken and not properly retried. This causes those requests to
potentially never get woken again, if we race.
