[PATCH] produce a warning on unchecked inode_setattr use
The patch below uses the new-in-gcc-3.4 option to generate a warning on
unchecked results of marked functions, and applies this to the
inode_setattr function (which based on recent bk commits HAS to be checked
for it's return value for correct operation). A warning looks like this:
fs/ext2/inode.c:1279: warning: ignoring return value of 'inode_setattr', declared with attribute warn_unused_result
