Subject: [PATCH] fs: sysv: Fix sysv_nblocks() returns wrong value
Date: Fri, 9 Dec 2022 18:04:48 +0800 [thread overview]
Message-ID: <20221209100448.176857-1-chenzhongjin@huawei.com> (raw)
sysv_nblocks() returns 'blocks' rather than 'res', which only counting
the number of triple-indirect blocks and causing sysv_getattr() gets a
wrong result.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
