From: Julia Lawall <julia@xxxxxxx> ARRAY_SIZE is more concise to use when the size of an array is divided by the size of its type or the size of its first element. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @i@ @@ #include <linux/kernel.h> @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/message/fusion/mptbase.c | 12 ++++++------ 1 files changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/message/fusion/mptbase.c b/drivers/message/fusion/mptbase.c index d6a0074..7a313f3 100644 --- a/drivers/message/fusion/mptbase.c +++ b/drivers/message/fusion/mptbase.c @@ -4563,7 +4563,7 @@ WaitForDoorbellReply(MPT_ADAPTER *ioc, int howlong, int sleepFlag) failcnt++; hword = le16_to_cpu(CHIPREG_READ32(&ioc->chip->Doorbell) & 0x0000FFFF); /* don't overflow our IOC hs_reply[] buffer! */ - if (u16cnt < sizeof(ioc->hs_reply) / sizeof(ioc->hs_reply[0])) + if (u16cnt < ARRAY_SIZE(ioc->hs_reply)) hs_reply[u16cnt] = hword; CHIPREG_WRITE32(&ioc->chip->IntStatus, 0); } @@ -7176,7 +7176,7 @@ union loginfo_type { sas_loginfo.loginfo = log_info; if ((sas_loginfo.dw.bus_type != 3 /*SAS*/) && - (sas_loginfo.dw.originator < sizeof(originator_str)/sizeof(char*))) + (sas_loginfo.dw.originator < ARRAY_SIZE(originator_str))) return; originator_desc = originator_str[sas_loginfo.dw.originator]; @@ -7185,21 +7185,21 @@ union loginfo_type { case 0: /* IOP */ if (sas_loginfo.dw.code < - sizeof(iop_code_str)/sizeof(char*)) + ARRAY_SIZE(iop_code_str)) code_desc = iop_code_str[sas_loginfo.dw.code]; break; case 1: /* PL */ if (sas_loginfo.dw.code < - sizeof(pl_code_str)/sizeof(char*)) + ARRAY_SIZE(pl_code_str)) code_desc = pl_code_str[sas_loginfo.dw.code]; break; case 2: /* IR */ if (sas_loginfo.dw.code >= - sizeof(ir_code_str)/sizeof(char*)) + ARRAY_SIZE(ir_code_str)) break; code_desc = ir_code_str[sas_loginfo.dw.code]; if (sas_loginfo.dw.subcode >= - sizeof(raid_sub_code_str)/sizeof(char*)) + ARRAY_SIZE(raid_sub_code_str)) break; if (sas_loginfo.dw.code == 0) sub_code_desc = -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
