From cf420048b3b2af9ce928d35cc5455c646c9dd2f7 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 16 Feb 2012 17:50:06 +0000 Subject: [PATCH] Delete the __FD_*() funcs for operating on fd_set from linux/time.h Delete the __FD_*() functions for operating on fd_set structs from linux/time.h as they're no longer used within the kernel with the preceding patch and are not exported to userspace. Whilst linux/time.h *does* export the FD_*() equivalents as wrappers around __FD_*(), userspace provides its own definition of __FD_*(). Note that the definition of FD_ZERO() in linux/time.h may not be used with the fd_sets associated with struct fdtable as the fd_set may have been allocated in a truncated fashion.
