From: Tetsuo Handa on 11 Sep 2009 03:40 Hello. I changed CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE to 2000 and did # insmod /lib/modules/2.6.31/kernel/drivers/edac/r82600_edac.ko insmod: error inserting '/lib/modules/2.6.31/kernel/drivers/edac/r82600_edac.ko': -1 Unknown symbol in module # echo scan > /sys/kernel/debug/kmemleak # dmesg r82600_edac: Unknown symbol edac_mc_del_mc r82600_edac: Unknown symbol edac_mc_add_mc r82600_edac: Unknown symbol edac_pci_create_generic_ctl r82600_edac: Unknown symbol edac_mc_alloc r82600_edac: Unknown symbol edac_mc_find_csrow_by_page r82600_edac: Unknown symbol edac_mc_free r82600_edac: Unknown symbol edac_mc_handle_ce r82600_edac: Unknown symbol edac_mc_handle_ue r82600_edac: Unknown symbol edac_pci_release_generic_ctl kmemleak: 1 new suspected memory leaks (see /sys/kernel/debug/kmemleak) # tail -n 4 /sys/kernel/debug/kmemleak unreferenced object 0xd643a788 (size 32): comm "insmod", pid 2854, jiffies 4294791099 backtrace: [<ffffffff>] 0xffffffff Is this real memory leak?
