__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.
