From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

The aic7xxx driver will automatically + vary this number based on device behavior. For devices with a + fixed maximum, the driver will eventually lock to this maximum + and display a console message inidicating this value. + + Due to resource allocation issues in the Linux SCSI mid-layer, using + a high number of commands per device may result in memory allocation + failures when many devices are attached to the system. For this reason, + the default is set to 32. Higher values may result in higer performance + on some devices.
