The patch titled Subject: tools/vm/slabinfo: add option to sort by partial slabs has been removed from the -mm tree. Its filename was tools-vm-slabinfo-add-option-to-sort-by-partial-slabs.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: "Tobin C. Harding" <tobin@xxxxxxxxxx> Subject: tools/vm/slabinfo: add option to sort by partial slabs We would like to get a better view of the level of fragmentation within the SLUB allocator. Total number of partial slabs is an indicator of fragmentation. Add a command line option (-P | --partial) to sort the slab list by total number of partial slabs.
