The warning is invalid because the parameter chunksize passed from ocfs2_info_freefrag_scan_chain-->ocfs2_info_update_ffg is guaranteed to be positive. So __ilog2_u32 cannot return -1. fs/ocfs2/ioctl.c: In function 'ocfs2_info_update_ffg': fs/ocfs2/ioctl.c:411:17: warning: array subscript is below array bounds [-Warray-bounds] hist->fc_chunks[index]++; ^ fs/ocfs2/ioctl.c:411:17: warning: array subscript is below array bounds [-Warray-bounds] Link: http://lkml.kernel.org/r/1524655799-12112-1-git-send-email-thunder.leizhen@huawei.comSigned-off-by:
