mm: introduce kmemleak_update_trace()

2014-06-06T23:08:17+00:00

The memory allocation stack trace is not always useful for debugging a memory leak (e.g. radix_tree_preload). This function, when called, updates the stack trace for an already allocated object.

Documentation/kmemleak.txt: updates

2014-04-03T23:21:27+00:00

Update Documentatin/kmemleak.txt to reflect the following changes: Commit b69ec42b1b19 ("Kconfig: clean up the long arch list for the DEBUG_KMEMLEAK config option") made it so that we can't check supported architectures by read Kconfig.debug. Commit 85d3a316c71 ("kmemleak: use rbtree instead of prio tree") converted kmemleak to use rbtree instead of prio tree.

kmemleak: allow freeing internal objects after kmemleak was disabled

2014-04-03T23:20:50+00:00

Currently if kmemleak is disabled, the kmemleak objects can never be freed, no matter if it's disabled by a user or due to fatal errors. Those objects can be a big waste of memory. OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 1200264 1197433 99% 0.30K 46164 26 369312K kmemleak_object With this patch, after kmemleak was disabled you can reclaim memory with: # echo clear > /sys/kernel/debug/kmemleak Also inform users about this with a printk.

kmemleak: Handle percpu memory allocation

2011-12-02T16:12:42+00:00

This patch adds kmemleak callbacks from the percpu allocator, reducing a number of false positives caused by kmemleak not scanning such memory blocks. The percpu chunks are never reported as leaks because of current kmemleak limitations with the __percpu pointer not pointing directly to the actual chunks.

Documentation: update kmemleak supported archs

2011-06-16T04:52:50+00:00

Instead of listing the architectures that are supported by kmemleak in Documentation/kmemleak.txt, just refer people to the list of supported architecutures in lib/Kconfig.debug so that Documentation/kmemleak.txt does not need more updates for this.

Documentation: update kmemleak arch. info

2011-04-05T00:51:46+00:00
