2.6.28-stable review patch. If anyone has any objections, please let us know. ------------------ From: Aneesh Kumar K.V (cherry picked from commit 0087d9fb3f29f59e8d42c8b058376d80e5adde4c) With nodelalloc option we need to update the dirty block counter on block allocation failure. This is needed because we increment the dirty block counter early in the block allocation phase. Without the patch s_dirty_blocks_counter goes wrong so that filesystem's free blocks decreases incorrectly.
