Eric Whitney 3258386aba ext4: reset retry counter when ext4_alloc_file_blocks() makes progress ... Change the retry policy in ext4_alloc_file_blocks() to allow for a full retry cycle whenever a portion of an allocation request has been fulfilled. A large allocation request often results in multiple calls to ext4_map_blocks(), each of which is potentially subject to a temporary ENOSPC condition and retry cycle. The current code only allows for a single retry cycle. This patch does not address a known bug or reported complaint. However, it should make block allocation for fallocate and zero range more robust. In addition, simplify the conditional controlling the allocation while loop, where testing len alone is sufficient. Remove the assignment to ret2 in the error path after the call to ext4_map_blocks() since its value isn't subsequently used.
