Matthew Ahrens 435dc4baab Assertion failure when logging large output of channel program ... The output of ZFS channel programs is logged on-disk in the zpool history, and printed by `zpool history -i`. Channel programs can use 10MB of memory by default, and up to 100MB by using the `zfs program -m` flag. Therefore their output can be up to some fraction of 100MB. In addition to being somewhat wasteful of the limited space reserved for the pool history (which for large pools is 1GB), in extreme cases this can result in a failure of `ASSERT(length <= DMU_MAX_ACCESS);` in `dmu_buf_hold_array_by_dnode()`. This commit limits the output size that will be logged to 1MB. Larger outputs will not be logged, instead a entry will be logged indicating the size of the omitted output.
