/home/bor/src/linux-git/fs/reiserfs/procfs.c: In function 'show_journal':
/home/bor/src/linux-git/fs/reiserfs/procfs.c:393: warning: format '%u' 
expects type 'unsigned int', but argument 22 has type 'long unsigned int'
  LD [M]  fs/reiserfs/reiserfs.o


Argument 22 is journal->j_last_flush_trans_id. As far as I can tell in all 
contexts where it is used it is assigned unsigned int (and journal->trans_id 
itself is unsigned int as well). So is this patch appropriate? It compiles 
cleanly, but I am a bit scared to test it on my sole root reiserfs :)

Subject: [PATCH] reiserfs: Make j_last_flush_trans_id unsigned int
From: Andrey Borzenkov <arvidjaar@mail.ru>

j_last_flush_trans_id is always assigned unsigned int value; so make it
unsigned int as well. It also removes this warning:
