Change Details

``` The loop 'skip clean blocks' checking for the clean blocks in the dirty pages might end up without setting the in_hole locals value to false, if we started right at EOF. In this case there is no dirty blocks to write out, and prev_offset is equal to next_offset, failing the assertion. Instead of asserting prev_offset < next_offset, we must skip the write.

``` vnode_pager_generic_putpages(): correctly handle clean block at EOF The loop 'skip clean blocks' checking for the clean blocks in the dirty pages might end up setting the in_hole to true when exactly at EOF at the middle of the block, without advancing the prev_offset value. Then the next block is not dirty, and next_offset is clipped back to poffset + maxsize, equal to prev_offset, failing the assertion. Instead of asserting prev_offset < next_offset, we must skip the write. Reported by: asomers PR: 276191 ``` ``` vnode_pager_generic_putpages(): rename maxblksz local to max_offset ```
