Note - this bug affects upstream 2.6.29 as well, but I believe the
Debian 2.6.28 packages are ok (the mips-specific changes for
CVE-2009-0029 happened later).

Subject: syscall wrapper changes cause llseek failure
I had a report today of a possible regression caused by the syscall
wrapper changes. On a pristine 64-bit 2.6.29-rc8 kernel, llseek seems
to always return -EINVAL. This was noticed on one of the Debian
infrastructure machines where, after an upgrade, e2fsck began failing
with errors like:
Error reading block 524290 (Invalid argument) while getting next inode
from scan. Ignore error<y>?
I believe this is due to the syswrapper changes because its easy to
reproduce with Debian's 2.6.26 patched w/ the syswrapper changes, but
goes away if we back the syswrapper changes back out.
I compared strace output between a working and failing kernel:
