[PATCH v11 10/10] ref_tracker: eliminate the ref_tracker_dir name field

Now that we have dentries and the ability to create meaningful symlinks to them, don't keep a name string in each tracker. Switch the output format to print "class@address", and drop the name field. Also, add a kerneldoc header for ref_tracker_dir_init(). Signed-off-by: Jeff Layton --- drivers/

[PATCH v11 09/10] net: add symlinks to ref_tracker_dir for netns

After assigning the inode number to the namespace, use it to create a unique name for each netns refcount tracker with the ns.inum and net_cookie values in it, and register a symlink to the debugfs file for it. init_net is registered before the ref_tracker dir is created, so add a late_initcall()

Currently, there is no convenient way to see the info that the ref_tracking infrastructure collects. Attempt to create a file in debugfs when called from ref_tracker_dir_init(). The file is given the name "class@%px", as having the unmodified address is helpful for debugging. This should be safe s

In a later patch, we'll be adding a 3rd mechanism for outputting ref_tracker info via seq_file. Instead of a conditional, have the caller set a pointer to an output function in struct ostream. As part of this, the log prefix must be explicitly passed in, as it's too late for the pr_fmt macro. Revi

[PATCH v11 05/10] ref_tracker: add a static classname string to each ref_tracker_dir

A later patch in the series will be adding debugfs files for each ref_tracker that get created in ref_tracker_dir_init(). The format will be "class@%px". The current "name" string can vary between ref_tracker_dir objects of the same type, so it's not suitable for this purpose. Add a new "class" st

[PATCH v11 01/10] i915: only initialize struct ref_tracker_dir once

I got some warnings from the i915 CI with the ref_tracker debugfs patches applied, that indicated that these ref_tracker_dir_init() calls were being called more than once. If references were held on these objects between the initializations, then that could lead to leaked ref tracking objects. Sin

[PATCH v11 02/10] ref_tracker: don't use %pK in pr_ostream() output

As Thomas Weißschuh points out [1], it is now preferable to use %p instead of hashed pointers with printk(), since raw pointers should no longer be leaked into the kernel log. Change the ref_tracker infrastructure to use %p instead of %pK in its formats. [1]: https://lore.kernel.org/netdev/202504
