Andreas Gruenbacher 208200e573 gfs2: Fix filesystem block deallocation for short writes ... [ Upstream commit d031a8866e709c9d1ee5537a321b6192b4d2dc5b ] When a write cannot be carried out in full, gfs2_iomap_end() releases blocks that have been allocated for this write but haven't been used. To compute the end of the allocation, gfs2_iomap_end() incorrectly rounded the end of the attempted write down to the next block boundary to arrive at the end of the allocation. It would have to round up, but the end of the allocation is also available as iomap->offset + iomap->length, so just use that instead. In addition, use round_up() for computing the start of the unused range.
