Hi,
here is a set of trivial patches which encapsulate the 'sb->s_dirt' variable
into 3 new helper VFS functions:
* static inline void mark_sb_dirty(struct super_block *sb)
* static inline void mark_sb_clean(struct super_block *sb)
* static inline int sb_is_dirty(struct super_block *sb)
With these patches the whole Linux kernel tree has only 3 places where
'sb->s_dirt' is referred.
These patches were sent as part of periodic write-back optimization series here:
http://marc.info/?l=linux-kernel&m=124342331127886&...
Because of the overlap with Jens' "per-bdi write-back" work, I have to work
on top of Jens' patches. However, it would be easier for me if my preparation
"abstracting sb->s_dirt" patches were merged earlier, at 2.6.31 merge window.
I think they make sense in general. I would then continue working on the second
part separately.
Thanks.
