Hello, I am trying to port the e2compr (transparent file compression on ext2 - see http://www.alizt.com/) patch to the linux-2.4.20rc2. The original patch applies to 2.4.17, and uses wake_up(&page->wait); in fs/ext2/inode.c The problem is that there was a patch included in 2.4.19pre2 which removed page->wait, and replaced the above call with wake_up_page(page); Then shortly aftewards (also 2.4.19pre*) wake_up_page was removed... So I replaced the two wake_up(&page->wait) in inode.c by the old definition of wake_up_page, which was: wake_up(page_waitqueue(page)); (and I also added EXPORT_SYMBOL(page_waitqueue) in mm/filemap.c) but still doesn't work, i get an error: inode.c:61: multiple storage classes in declaration of `page_waitqueue' inode.c:61: warning: `page_waitqueue' used but never defined Ok, i am doing something stupid with the declarations (don't know what anyway), but i would also like to know which is the correct way to replace that call because i guess the data integrity could depend on it ;-) Thanks for your help, and please CC me as i am not subscribed presently.
