Oliver Glitta 5cf909c553 mm/slub: use stackdepot to save stack trace in objects ... Many stack traces are similar so there are many similar arrays. Stackdepot saves each unique stack only once. Replace field addrs in struct track with depot_stack_handle_t handle. Use stackdepot to save stack trace. The benefits are smaller memory overhead and possibility to aggregate per-cache statistics in the following patch using the stackdepot handle instead of matching stacks manually. [ vbabka@suse.cz: rebase to 5.17-rc1 and adjust accordingly ] This was initially merged as commit 788691464c and reverted by commit ae14c63a9f due to several issues, that should now be fixed. The problem of unconditional memory overhead by stackdepot has been addressed by commit 2dba5eb1c7 ("lib/stackdepot: allow optional init and stack_table allocation by kvmalloc()"), so the dependency on stackdepot will result in extra memory usage only when a slab cache tracking is actually enabled, and not for all CONFIG_SLUB_DEBUG builds. The build failures on some architectures were also addressed, and the reported issue with xfs/433 test did not reproduce on 5.17-rc1 with this patch.
