[PATCH 3/7] cifs: smbd: Return -EINVAL when the number of iovs exceeds SMBDIRECT_MAX_SGE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Long Li <longli@xxxxxxxxxxxxx>

While it's not friendly to fail user processes that issue more iovs
than we support, at least we should return the correct error code so the
user process gets a chance to retry with smaller number of iovs.
