  "message": "write-back: fix nr_to_write counter\n\nCommit 05fe478dd04e02fa230c305ab9b5616669821dd3 introduced some\n@wbc-\u003enr_to_write breakage.\n\nIt made the following changes:\n 1. Decrement wbc-\u003enr_to_write instead of nr_to_write\n 2. Decrement wbc-\u003enr_to_write _only_ if wbc-\u003esync_mode \u003d\u003d WB_SYNC_NONE\n 3. If synced nr_to_write pages, stop only if if wbc-\u003esync_mode \u003d\u003d\n    WB_SYNC_NONE, otherwise keep going.\n\nHowever, according to the commit message, the intention was to only make\nchange 3.  Change 1 is a bug.  Change 2 does not seem to be necessary,\nand it breaks UBIFS expectations, so if needed, it should be done\nseparately later.  And change 2 does not seem to be documented in the\ncommit message.\n\nThis patch does the following:\n 1. Undo changes 1 and 2\n 2. Add a comment explaining change 3 (it very useful to have comments\n    in _code_, not only in the commit).\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\nAcked-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
