Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will

The previous code: fcntl (fd, F_SETFL, O_NONBLOCK) was technically incorrect, because it would have reset any other flags on the file descriptor.

Dear Sir, I was trying to install bridge as we are installing scps gateway in our testbed.This requires us to install the bridge. Our Linux version is 2.4.18 ~3 and we are using redhat 7.2 Please let me know which is the bridge I should install and how to configure it. Before configuring the bridge what I should check in my configuration. Thanks for your time, Sincerely Rama ===== I hear

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
