f2fs: support synchronous gc in ioctl This patch drops in batches gc triggered through ioctl, since user can easily control the gc by designing the loop around the ->ioctl. We support synchronous gc by forcing using FG_GC in f2fs_gc, so with it, user can make sure that in this round all blocks gced were persistent in the device until ioctl returned.
