Currently shrinkers are anonymous objects. For debugging purposes they can be identified by count/scan function names, but it's not always useful: e.g. for superblock's shrinkers it's nice to have at least an idea of to which superblock the shrinker belongs. This commit adds names to shrinkers. register_shrinker() and prealloc_shrinker() functions are extended to take a format and arguments to master a name. In some cases it's not possible to determine a good name at the time when a shrinker is allocated. For such cases shrinker_debugfs_rename() is provided. After this change the shrinker debugfs directory looks like: $ cd /sys/kernel/debug/shrinker/ $ ls dqcache-16 sb-hugetlbfs-17 sb-rootfs-2 sb-tmpfs-49 kfree_rcu-0 sb-hugetlbfs-33 sb-securityfs-6 sb-tracefs-13 sb-aio-20 sb-iomem-12 sb-selinuxfs-22 sb-xfs:vda1-36 sb-anon_inodefs-15 sb-mqueue-21 sb-sockfs-8 sb-zsmalloc-19 sb-bdev-3 sb-nsfs-4 sb-sysfs-26 shadow-18 sb-bpf-32 sb-pipefs-14 sb-tmpfs-1 thp_deferred_split-10 sb-btrfs:vda2-24 sb-proc-25 sb-tmpfs-27 thp_zero-9 sb-cgroup2-30 sb-proc-39 sb-tmpfs-29 xfs_buf-vda1-37 sb-configfs-23 sb-proc-41 sb-tmpfs-35 xfs_inodegc-vda1-38 sb-dax-11 sb-proc-45 sb-tmpfs-40 zspool-zram0-34 sb-debugfs-7 sb-proc-46 sb-tmpfs-42 sb-devpts-28 sb-proc-47 sb-tmpfs-43 sb-devtmpfs-5 sb-pstore-31 sb-tmpfs-44 Signed-off-by: Roman Gushchin <roman.gushchin@linux.dev> --- arch/x86/kvm/mmu/mmu.c | 2 +- drivers/android/binder_alloc.c | 2 +- drivers/gpu/drm/i915/gem/i915_gem_shrinker.c | 3 +- drivers/gpu/drm/msm/msm_gem_shrinker.c | 2 +- .../gpu/drm/panfrost/panfrost_gem_shrinker.c | 2 +- drivers/gpu/drm/ttm/ttm_pool.c | 2 +- drivers/md/bcache/btree.c | 2 +- drivers/md/dm-bufio.c | 3 +- drivers/md/dm-zoned-metadata.c | 4 +- drivers/md/raid5.c | 2 +- drivers/misc/vmw_balloon.c | 2 +- drivers/virtio/virtio_balloon.c | 2 +- drivers/xen/xenbus/xenbus_probe_backend.c | 2 +- fs/btrfs/super.c | 2 + fs/erofs/utils.c | 2 +- fs/ext4/extents_status.c | 3 +- fs/f2fs/super.c | 2 +- fs/gfs2/glock.c | 2 +- fs/gfs2/main.c | 2 +- fs/jbd2/journal.c | 3 +- fs/mbcache.c | 2 +- fs/nfs/nfs42xattr.c | 7 ++- fs/nfs/super.c | 2 +- fs/nfsd/filecache.c | 2 +- fs/nfsd/nfscache.c | 3 +- fs/quota/dquot.c | 2 +- fs/super.c | 6 +- fs/ubifs/super.c | 2 +- fs/xfs/xfs_buf.c | 3 +- fs/xfs/xfs_icache.c | 2 +- fs/xfs/xfs_qm.c | 3 +- include/linux/shrinker.h | 12 +++- kernel/rcu/tree.c | 2 +- mm/huge_memory.c | 4 +- mm/shrinker_debug.c | 47 ++++++++++++++- mm/vmscan.c | 58 ++++++++++++++++++- mm/workingset.c | 2 +- mm/zsmalloc.c | 3 +- net/sunrpc/auth.c | 2 +- 39 files changed, 165 insertions(+), 45 deletions(-)
