I don't think we're actually likely to hit this limit but if we do then the comparison should be done as size_t. The original code is equivalent to: len = strlen(sptr) % USHRT_MAX;
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> --- I was told this patch "has already made it upstream via the v9fs pull." but it must have been dropped accidentally. Originally sent on Sat, Jan 15, 2011.
