First, I need to fix a mistake in comment lines that is lead by "+" in comments, It wouldn't cause the compiler warning, but it seems not good; As the latest coding-style instruction, for the multi-line comment is .. code-block:: c /* * This is the preferred style for multi-line * comments in the Linux kernel source code. * Please use it consistently. * * Description: A column of asterisks on the left side, * with beginning and ending almost-blank lines. */ But for net/ and drivers/net the perferred style for multi-line is: .. code-block:: c /* The preferred comment style for files in net/ and drivers/net * looks like this. * * It is nearly the same as the generally preferred comment * style, * but there is no initial almost-blank line. */ For hpsa, there are two types of comment sections in hpsa code, I choose the first style for all comment sections; Signed-off-by: James Wang <jnwang@linux.alibaba.com> --- drivers/scsi/hpsa.c | 199 ++++++++++++++++++++++++++++++++++------------------ 1 file changed, 131 insertions(+), 68 deletions(-)
