Hi, I have kmemleak detector enabled since 3.7.1 but now, with 3.7.4 I get the following:
comm "X", pid 5475, jiffies 4294992244 (age 133695.910s) hex dump (first 32 bytes): 69 39 31 35 40 70 63 69 3a 30 30 30 30 3a 30 30 i915@pci:0000:00 3a 30 32 2e 30 00 6b 6b 6b 6b 6b 6b 6b 6b 6b a5 :02.0.kkkkkkkkk. backtrace: [<ffffffff815b4aad>] kmemleak_alloc+0x21/0x3e [<ffffffff81110352>] slab_post_alloc_hook+0x28/0x2a [<ffffffff8111288a>] __kmalloc+0xf2/0x104 [<ffffffffa0077c0b>] drm_pci_set_busid+0xf6/0x12b [drm] [<ffffffffa0072a04>] drm_setversion+0xaf/0x177 [drm] [<ffffffffa00707b1>] drm_ioctl+0x309/0x3c9 [drm] [<ffffffff81125e7e>] do_vfs_ioctl+0x462/0x4a3 [<ffffffff81125f06>] sys_ioctl+0x47/0x69 [<ffffffff815dd716>] system_call_fastpath+0x1a/0x1f [<ffffffffffffffff>] 0xffffffffffffffff
