BTW. it\nmay not completely write all pages out, so I_DIRTY_PAGES would get set\nagain.\n\nThis is a standard pattern used throughout the kernel\u0027s writeback caches\n(I_SYNC ~\u003d I_WRITEBACK, if that makes it clearer).\n\nAnd so it is not possible to determine an inode\u0027s dirty status just by\nchecking I_DIRTY bits.
