There are several places where we add together NR_UNSTABLE_FS and NF_FILE_DIRTY:
sync_inodes_sb() balance_dirty_pages() wakeup_pdflush() wb_kupdate() prefetch_suitable() I can trace a standard codepath where it seems both of these are set on the same page: nfs_file_aops.commit_write -> nfs_commit_write nfs_updatepages nfs_writepage_setup nfs_wb_page nfs_wb_page_priority nfs_writepage_locked nfs_flush_mapping nfs_flush_list nfs_flush_multi nfs_write_partial_ops.rpc_call_done nfs_writeback_done_partial nfs_writepage_release nfs_reschedule_unstable_write nfs_mark_request_commit incr NR_UNSTABLE_NFS nfs_file_aops.commit_write -> nfs_commit_write nfs_updatepage __set_page_dirty_nobuffers incr NF_FILE_DIRTY This is the standard code path that derives from sys_write(). Can someone either show how this code sequence can't happen, or confirm for me that there's a bug? -- Ethan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
