But, the async_write\nflag is now used as a marker by commit 7f42ec394156 (\"nilfs2: fix issue\nwith race condition of competition between segments for dirty blocks\") as\na means of resolving double list insertion of dirty blocks in\nnilfs_lookup_dirty_data_buffers() and nilfs_lookup_node_buffers() and the\nresulting crash.\n\nThis modification is safe as long as it is used for file data and b-tree\nnode blocks where the page caches are independent. However, it was\nirrelevant and redundant to also introduce async_write for segment summary\nand super root blocks that share buffers with the backing device. This\nled to the possibility that the BUG_ON check in end_buffer_async_write\nwould fail as described above, if independent writebacks of the backing\ndevice occurred in parallel.\n\nThe use of async_write for segment summary buffers has already been\nremoved in a previous change.\n\nFix this issue by removing the manipulation of the async_write flag for\nthe remaining super root block buffer." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
