35 * that memory location is free to be reused at any time. Thus it may

37 *
38 * This feature only ensures the memory location backing the object

41 *
42 * rcu_read_lock()

57 * from its address obtained without the usual locking. We can lock
58 * the structure to stabilize it and check it's still at the given address,
59 * only if we can be sure that the memory has not been meanwhile reused
60 * for some other kind of object (which our subsystem's lock might corrupt).
61 *

389 * kmalloc - allocate memory
390 * @size: how many bytes of memory are required.
391 * @flags: the type of memory to allocate.
392 *
393 * kmalloc is the normal method of allocating memory
394 * for objects smaller than page size in the kernel.
395 *
396 * The @flags argument may be one of:
397 *
398 * %GFP_USER - Allocate memory on behalf of user. May sleep.
399 *
400 * %GFP_KERNEL - Allocate normal kernel ram. May sleep.
401 *
402 * %GFP_ATOMIC - Allocation will not sleep. May use emergency pools.
403 * For example, use this inside interrupt handlers.
404 *
405 * %GFP_HIGHUSER - Allocate pages from high memory.
406 *
407 * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
408 *
409 * %GFP_NOFS - Do not make any fs calls while trying to get memory.
410 *
411 * %GFP_NOWAIT - Allocation will not sleep.
412 *
413 * %__GFP_THISNODE - Allocate node-local memory only.
414 *
415 * %GFP_DMA - Allocation suitable for DMA.
416 * Should only be used for kmalloc() caches. Otherwise, use a
417 * slab created with SLAB_DMA.
418 *
419 * Also it is possible to set different flags by OR'ing
420 * in one or more of the following additional @flags:
421 *
422 * %__GFP_COLD - Request cache-cold pages instead of
423 * trying to return cache-warm pages.
424 *
425 * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
426 *
427 * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
428 * (think twice before using).
429 *
430 * %__GFP_NORETRY - If memory is not immediately available,
431 * then give up at once.
432 *
433 * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
434 *
435 * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
436 *
437 * There are other flags available as well, but these are not intended
438 * for general use, and so are not documented here. For a full list of
439 * potential flags, always refer to linux/gfp.h.

Here is an explanation of a rule violation arisen while checking your driver against a corresponding kernel.
Note that it may be false positive, i.e. there isn't a real error indeed. Please analyze a given error trace and related source code to understand whether there is an error in your driver.
Error trace column contains a path on which the given rule is violated. You can expand/collapse some entity classes by clicking on corresponding checkboxes in a main menu or in an advanced Others menu. Also you can expand/collapse each particular entity by clicking on +/-. In hovering on some entities you can see some tips. Also the error trace is bound with related source code. Line numbers may be shown as links on the left. You can click on them to open corresponding lines in source code.
Source code column contains a content of files related with the error trace. There is source code of your driver (note that there are some LDV modifications at the end), kernel headers and rule model. Tabs show a currently opened file and other available files.
