Linux-2.4.2 patch

“Ok, the patch looks huge (it’s a meg and a half compressed, 6+ megs
uncompressed), but most of the patch by far is S/390 updates and the
new Cris architecture.”

                  Ok, the patch looks huge (it's a meg and a half compressed, 6+ megs
                  uncompressed), but most of the patch by far is S/390 updates and the
                   new Cris architecture.

                  The biggest real changes that impact normal users are the two bugs
                   that could corrupt your harddisk. The IDE driver bug that Russell
                   found has, to my knowledge, never been shown to happen on anything
                   but his ARM machine, but for all we know it could be quite bad even
                   on x86. Similarly, the elevator bug could cause corruption, but
                   probably has not actually bit people in practice. But both are
                   definitely deadly at least in theory even on bog-standard common PC
                   hardware.

                  The reiserfs fix should hopefully make the "null bytes in log-files"
                  problem a non-issue, and along with the smbfs/HIGHMEM thing it is
                  certainly important for those that it can affect.
