966 Since opening block devices cannot happen under s_umount because of lock967 ordering requirements s_umount is now dropped while opening block devices and972 would hold s_umount they would wait until the superblock became either born or975 Since the new logic drops s_umount concurrent mounters could grab s_umount and977 mechanism without having to hold s_umount.
182 ops s_umount note203 ->statfs() has s_umount (shared) when called by ustat(2) (native or204 compat), but that's an accident of bad API; s_umount is used to pin
