When calculating space needed for SA_BONUS buffers, hdrsize is always rounded up to next 8-aligned boundary. However, in two places the round up was done against sum of 'total' plus hdrsize. On the other hand, hdrsize increments by 4 each time, which means in certain conditions, we would end up returning with will_spill == 0 and (total + hdrsize) larger than full_space, leading to a failed assertion because it's invalid for dmu_set_bonus.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
