NAME

6       __mark_inode_dirty - internal function
7

SYNOPSIS

9       void __mark_inode_dirty(struct inode * inode, int flags);
10

ARGUMENTS

12       inode
13           inode to mark
14
15       flags
16           what kind of dirty (i.e. I_DIRTY_SYNC) Mark an inode as dirty.
17           Callers should use mark_inode_dirty or mark_inode_dirty_sync.
18

DESCRIPTION

20       Put the inode on the super block's dirty list.
21
22       CAREFUL! We mark it dirty unconditionally, but move it onto the dirty
23       list only if it is hashed or if it refers to a blockdev. If it was not
24       hashed, it will never be added to the dirty list even if it is later
25       hashed, as it will have been marked dirty already.
26
27       In short, make sure you hash any inodes _before_ you start marking them
28       dirty.
29
30       Note that for blockdevs, inode->dirtied_when represents the dirtying
31       time of the block-special inode (/dev/hda1) itself. And the
32       ->dirtied_when field of the kernel-internal blockdev inode represents
33       the dirtying time of the blockdev's pages. This is why for
34       I_DIRTY_PAGES we always use page->mapping->host, so the page-dirtying
35       time is recorded in the internal blockdev inode.
