From d96336b05d718b03ff03c94c0dc0cc283a29d534 Mon Sep 17 00:00:00 2001 From: Josh Hunt Date: Mon, 27 Dec 2010 13:46:38 -0800 Subject: ext2: Resolve 'dereferencing pointer to incomplete type' when enabling EXT2_XATTR_DEBUG When I enable EXT2_XATTR_DEBUG in fs/ext2/xattr.c I get a build error stating the following: CC fs/ext2/xattr.o fs/ext2/xattr.c: In function 'ext2_xattr_cache_insert': fs/ext2/xattr.c:841: error: dereferencing pointer to incomplete type fs/ext2/xattr.c:846: error: dereferencing pointer to incomplete type make[2]: *** [fs/ext2/xattr.o] Error 1 make[1]: *** [fs/ext2] Error 2 make: *** [fs] Error 2 These lines reference ext2_xattr_cache->c_entry_count which is defined in struct mb_cache. struct mb_cache is currently only defined in fs/mbcache.c. Moving struct mb_cache definition to include/linux/mbcache.h to resolve the issue.
