Hi, During recent discussion on LKML over SLAB vs SLUB it was suggested by Jesper that it would be nice to have a tool to view the current fragmentation of the slab allocators. CC list for this set is taken from that thread. For SLUB we have all the information for this already exposed by the kernel and also we have a userspace tool for displaying this info: tools/vm/slabinfo.c Extend slabinfo to improve the fragmentation information by enabling sorting of caches by number of partial slabs. Also add cache list sorted in this manner to the output of `slabinfo -X`. thanks, Tobin. Tobin C. Harding (4): tools/vm/slabinfo: Order command line options tools/vm/slabinfo: Add partial slab listing to -X tools/vm/slabinfo: Add option to sort by partial slabs tools/vm/slabinfo: Add sorting info to help menu tools/vm/slabinfo.c | 118 ++++++++++++++++++++++++++------------------ 1 file changed, 70 insertions(+), 48 deletions(-) -- 2.21.0
