So far, the values of ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN were equal to MAXPATHLEN, which is 1024 on FreeBSD and 4096 on Linux. This wasn't ideal. Some of the surprising outcomes of this implementation are: 1. When creating a pool user property with zpool-set(8), libzfs makes sure that the length of the property's value is less than ZFS_MAXPROPLEN. However, the ZFS kernel module does not do that. Instead, it checks the length against ZAP_MAXVALUELEN. As a result, it is possible to create a property the length of which is going to be larger than zpool(8) is ready to read. 2. A pool user property created on Linux is too big to be read on FreeBSD. This change sets both ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN to ZAP_MAXVALUELEN, which is 8192 at the moment.
