Cover letter [PATCH 0/3] Fix problems about handling bio to plug when bio merged failed.
There are some problems about handling bio which merge to plug failed. Patch1 will avoid unnecessary plug should_sort test,although it's not a bug. Patch2 correct a bug when handle more devices,it leak some devices to trace plug-operation.
Because the patch2,so it's not necessary to sort when flush plug.Although patch2 has O(n*n) complexity,it's more than list_sort which has O(nlog(n)) complexity.But the plug list is unlikely too long,so i think patch3 can accept.
