[PATCH] Tiny reordering of some fields of task_struct

[PATCH] Tiny reordering of some fields of task_struct

[David Serrano]

(First post & first patch so please be kind O:))

Playing with some things (I'm just beginning with this whole kernel stuff) I
found that there are three filesystem-related members in task_struct that
aren't together:

/* file system info */
	int link_count, total_link_count;
/* ipc stuff */
	struct sysv_sem sysvsem;
/* CPU-specific state of this task */
	struct thread_struct thread;
/* filesystem information */
	struct fs_struct *fs;

[...]

/* journalling filesystem info */
	void *journal_info;

Perhaps there is some reason to have them as they are now but if that's not
the case, this joins them together. It's against 2.6.12-rc3.
