ioselectors_epoll: for NuttX, limit initial numFD to configured value. (#21421)
ioselectors: ioselectors_epoll: for NuttX, limit initial numFD to configured value. In the NuttX build config, there is a setting called "FS_NEPOLL_DESCRIPTORS". -------- config FS_NEPOLL_DESCRIPTORS int "Maximum number of default epoll descriptors for epoll_create1(2)" default 8 ---help--- The maximum number of default epoll descriptors for epoll_create1(2) -------- For NuttX, change the number of fd arrays allocated by newSelector() to that value.
