+0100 ocfs2: fix shift-out-of-bounds UBSAN bug in ocfs2_verify_volume() This patch addresses a shift-out-of-bounds error in the ocfs2_verify_volume() function, identified by UBSAN. The bug was triggered by an invalid s_clustersize_bits value (e.g., 1548), which caused the expression "1 << le32_to_cpu(di->id2.i_super.s_clustersize_bits)" to exceed the limits of a 32-bit integer, leading to an out-of-bounds shift.
