[PATCH 2/2] xfs: remove the extra processing of zero size in xfs_idata_realloc()

krealloc() does the free operation when the parameter new_size is 0, with ZERO_SIZE_PTR returned. Because all other places use NULL to check whether if_data is available or not, so covert it from ZERO_SIZE_PTR to NULL. Signed-off-by: Zhen Lei --- fs/xfs/libxfs/xfs_inode_fork.c | 9 + 1
