Commit b43abcbb ("scsi: fnic: Ratelimit printks to avoid flooding when vlan is not set by the switch.i") added printk_ratelimit() in front of a couple of debug-mode messages to reduce logging overrun when debugging the driver. The code: > if (printk_ratelimit()) > FNIC_FCS_DBG(KERN_DEBUG, fnic->lport->host, > "Start VLAN Discovery\n"); ends up calling printk_ratelimit() quite often, triggering many kernel messages about callbacks being supressed. The fix is to decompose FNIC_FCS_DBG(), then change the order of checks so that printk_ratelimit() is only called if driver debugging is enabled.

Instead of strcpy'ing into a stack buffer, just let additional_notice point to a string literal living in .rodata. This is better in a few ways: - Smaller .text - instead of gcc compiling the strcpys as a bunch of immediate stores (effectively encoding the string literal in the instruction stream), we only pay the price of storing the literal in .rodata. - Faster, because there's no string copying. - Smaller stack usage (with my compiler, 72 bytes instead of 176 for the sole caller, bnx2i_indicate_kcqe) Moreover, it's currently possible for additional_notice[] to get used uninitialized, so some random stack garbage would be passed to printk() - in the worst case without any '\0' anywhere in those 64 bytes. That could be fixed by initializing additional_notice[0], but the same is achieved here by initializing the new pointer variable to "". Also give the message pointer a similar treatment - there's no point making temporary copies on the stack of those two strings.
