Subject: ext2: fix debug reference to ext2_xattr_cache
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=32302085a8d90859c40cf1a5e8313f575d06ec75;p=linux.git

ext2: fix debug reference to ext2_xattr_cache

Fix a debug-only build error in ext2/xattr.c:

When building without extra debugging, (and with another patch that uses
no_printk() instead of <empty> for the ext2-xattr debug-print macros,
this build error happens:

../fs/ext2/xattr.c: In function ‘ext2_xattr_cache_insert’:
../fs/ext2/xattr.c:869:18: error: ‘ext2_xattr_cache’ undeclared (first use in
this function); did you mean ‘ext2_xattr_list’?
     atomic_read(&ext2_xattr_cache->c_entry_count));

Fix the problem by removing cached entry count from the debug message
since otherwise we'd have to export the mbcache structure just for that.
