13 years ago Changes to get it to compile under 2.6.37. These should help some in working out what the issues are. There is at least one proble with the below but this is as far as I can go. I am not familiar enough with kernel drivers to find the cause.

There needs to be a test for 2.6.37
I am not sure if REQ_WRITE is also needed and to confuse matters they are defined as the enable code.
#define REQ_WRITE (1 << __REQ_WRITE)
#define REQ_SYNC (1 << __REQ_SYNC)

#include <linux/version.h> //for LINUX_VERSION_CODE

# define DIO_RW_SYNCIO (1 << BIO_RW_SYNCIO)
#else
# define DIO_RW_SYNCIO (1 << BIO_RW_SYNC)
#endif /* HAVE_BIO_RW_SYNCIO */
/* 2.6.37 API change */
#if LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 36)
#undef DIO_RW_SYNCIO
#define DIO_RW_SYNCIO ( REQ_WRITE | REQ_SYNC )
nano nano module/zfs/vdev_disk.c
replace all:
(1 << DIO_RW_SYNCIO)
with:
DIO_RW_SYNCIO

Currently only 2.6.18-2.6.36 kernels are supported. The 2.6.37 kernel was release on Jan 4th 2011 and will start making its way in to distributions over the next several months. As expected roll your own distribution such as Gentoo are discovering this first, but it's only a matter of time before fedora/ubuntu distributions pick it up.
Currently the build fails as follows, if anyone is interested in working on these issues please drop me an email. If not we'll get to it time permitting.
