From 859d22f9c3924ab87b05ded8ba922abc298c1d43 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 31 Mar 2013 13:50:52 -0400 Subject: [PATCH] scsi_proc: make proc_scsi_host_open() preallocate a bigger buffer Some of the ->show_info() instances really spew a lot; it's not a problem wrt correctness (seq_read() will grow buffer and call the sucker again), but in this case it makes sense to start with a somewhat bigger one - they often do exceed one page worth of output.
