Subject: [PATCH V2 0/2] mtd: nandsim: fix error handling
Date: Thu, 25 Jun 2015 00:46:47 +0000 [thread overview]
Message-ID: <1435193209-54305-1-git-send-email-shengyong1@huawei.com> (raw)
V2:
Resend the patches against l2-mtd/master.
V1:
These 2 patches fix error handling when nandsim initialization fails.
In alloc_device(), if creating slab memory fails, free_device() will try
to destroy the slab memory without checking if it exists. PATCH 1 fixes
it.
If something goes wrong in init_nandsim(), it calls free_device() before
returning. However, the caller of init_nandsim() - ns_init_module() - also
does the cleanup by calling free_nandsim(). This causes double free. PATCH
2 fixes it.
Thanks,
Sheng
