Subject: [GIT PULL 3/8] lightnvm: Use u64 instead of __le64 for CPU visible side
Date: Mon, 11 Feb 2019 13:25:04 +0100 [thread overview]
Message-ID: <20190211122509.19910-4-mb@lightnvm.io> (raw)
In-Reply-To: <20190211122509.19910-1-mb@lightnvm.io>
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Sparse complains about using strict data types:
drivers/lightnvm/pblk-read.c:254:43: warning: incorrect type in assignment (different base types)
drivers/lightnvm/pblk-read.c:254:43: expected restricted __le64 <noident>
drivers/lightnvm/pblk-read.c:254:43: got unsigned long long [unsigned] [usertype] <noident>
drivers/lightnvm/pblk-read.c:255:29: warning: cast from restricted __le64
drivers/lightnvm/pblk-read.c:268:29: warning: cast from restricted __le64
drivers/lightnvm/pblk-read.c:328:41: warning: incorrect type in assignment (different base types)
drivers/lightnvm/pblk-read.c:328:41: expected restricted __le64 <noident>
drivers/lightnvm/pblk-read.c:328:41: got unsigned long long [unsigned] [usertype] <noident>
In the code it seems explicit that lba_list_mem and lba_list_media members
of struct pblk_pr_ctx are used on CPU side, which means they should not be
of strict types.
Change types of lba_list_mem and lba_list_media members to be u64.
