Description

[13625.206311] UBSAN: Undefined behaviour in /mnt/ssdraid/xyratex/lustre-wc-rel3/lustre/osd-ldiskfs/osd_io.c:1404:2
[13625.206363] shift exponent 4096 is too large for 32-bit type 'int'

The following piece of code seems to contain a typo:

        LASSERT(extent_bytes >= (1 << osd_sb(osd)->s_blocksize));
