Subject: Panic on kmemleak scan
Date: Mon, 11 Oct 2021 14:23:31 +0300 [thread overview]
Message-ID: <8ade5174-b143-d621-8c8e-dc6a1898c6fb@linaro.org> (raw)
Hello Mike,
commit a7259df767 ("memblock: make memblock_find_in_range method private") [1]
invokes a kernel panic while running kmemleak on OF platforms with nomaped
regions, basically it's similar to an issue reported and fixed earlier by [2]:
Unable to handle kernel paging request at virtual address ffff000021e00000
[...]
scan_block+0x64/0x170
scan_gray_list+0xe8/0x17c
kmemleak_scan+0x270/0x514
kmemleak_write+0x34c/0x4ac
I believe it would be a trivial problem to correct for you, thank you in
advance!
