I'm getting a lot of warnings about struct super_block in 2.6.23-rc2. Then, a compile error when compiling fs/drop_caches.o:
CC fs/drop_caches.o In file included from fs/drop_caches.c:7: include/linux/mm.h:1210: warning: 'struct super_block' declared inside parameter list include/linux/mm.h:1210: warning: its scope is only this definition or declaration, which is probably not what you want fs/drop_caches.c:17: error: conflicting types for 'drop_pagecache_sb' include/linux/mm.h:1210: error: previous declaration of 'drop_pagecache_sb' was here fs/drop_caches.c:28: error: conflicting types for 'drop_pagecache_sb' include/linux/mm.h:1210: error: previous declaration of 'drop_pagecache_sb' was here make[1]: *** [fs/drop_caches.o] Error 1 make: *** [fs] Error 2 I'm using Linus's tree, which is 2.6.23-rc2 plus all patches up to this commit: commit ac07860264bd2b18834d3fa3be47032115524cea Author: Jesper Juhl <[EMAIL PROTECTED]> Date: Wed Aug 8 16:31:30 2007 -0700 I didn't check if this is fixed already in the latest -mm.
