When compiling zfs from master, there's an error:

According to my research, that's because there's nothing about "BIO_RW_SYNC" in "configure" file, only about "BIO_RW_SYNCIO".

Use long-term supported kernel 2.6.35, it will compile without any issues. 36+ is not supported at the moment, i've had to rollback to earlier version too because of the compile problems. On 2.6.35.10 it builds perfectly, and as far as i see works quite stable.

Well, behlendorf mentions that this has been resolved for his branch - any chance of updating the sources to include his patches (See https://github.com/behlendorf/zfs/ issue 85)?

Anyway, even on 2.6.35 it's not stable. At least in filesystem mode it crashes very frequently.
