Hello Abhi Das,
The patch 39a725803bee: "gfs2: fix quota updates on block boundaries"
from Jun 2, 2015, leads to the following static checker warning:
fs/gfs2/quota.c:801 gfs2_adjust_quota()
warn: unsigned '()' is never less than zero.
fs/gfs2/quota.c
798 loc -= sizeof(q); /* gfs2_internal_read would've advanced the
loc ptr */
799 err = -EIO;
800 be64_add_cpu(&q.qu_value, change);
801 if (be64_to_cpu(q.qu_value) < 0)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Never true.
802 q.qu_value = 0; /* Never go negative on quota usage */
803 qd->qd_qb.qb_value = q.qu_value;
804 if (fdq) {
regards,
