__MARK_INODE_DIRTY(9)                     The Linux VFS                     __MARK_INODE_DIRTY(9)



NAME
       __mark_inode_dirty - internal function

SYNOPSIS
       void __mark_inode_dirty(struct inode * inode, int flags);

ARGUMENTS
       inode
           inode to mark

       flags
           what kind of dirty (i.e. I_DIRTY_SYNC) Mark an inode as dirty. Callers should use
           mark_inode_dirty or mark_inode_dirty_sync.

DESCRIPTION
       Put the inode on the super block's dirty list.

       CAREFUL! We mark it dirty unconditionally, but move it onto the dirty list only if it is
       hashed or if it refers to a blockdev. If it was not hashed, it will never be added to the
       dirty list even if it is later hashed, as it will have been marked dirty already.

       In short, make sure you hash any inodes _before_ you start marking them dirty.

       Note that for blockdevs, inode->dirtied_when represents the dirtying time of the
       block-special inode (/dev/hda1) itself. And the ->dirtied_when field of the
       kernel-internal blockdev inode represents the dirtying time of the blockdev's pages. This
       is why for I_DIRTY_PAGES we always use page->mapping->host, so the page-dirtying time is
       recorded in the internal blockdev inode.
