From: Martin Wilck <mwilck@xxxxxxxx> Hi Christophe, hi Ben, here are 3 patches I'd like to get reviewed before we create a pull request. The first two are related to complex SAS setups, the second one is to avoid accessing the root file system in a possible dangerous situation. Wrt 2/3: while testing it, I discovered that "I_T_nexus_loss_timeout" is a read-only sysfs attribute, therefore this code does nothing. I considered removing it altogether, observing that the attribute has been read-only as long as it existed (v2.6.17, 2006). I'd like some feedback beforehand, though, perhaps some distros use patched kernels that make this attribute r/w?
