Subject: Make /proc/slabinfo use seq_list_xxx helpers
From: Pavel Emelianov <[EMAIL PROTECTED]>
This entry prints a header in .start callback. This is OK, but the more
elegant solution would be to move this into the .show callback and use
seq_list_start_head() in .start one.
I have left it as is in order to make the patch just switch to new API and
noting more.
