.SH "ARGUMENTS"

.TP
\fIinode\fR
inode to mark

.TP
\fIflags\fR
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\&.

.SH "DESCRIPTION"

.PP
Put the inode on the super block's dirty list\&.

.PP
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\&.

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

.PP
This function *must* be atomic for the I_DIRTY_PAGES case \- \fBset_page_dirty\fR is called under spinlock in several places\&.

.PP
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\&.
