Subject: userns: Convert struct dquot_warn
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7b9c7321ca6b13d2baeb82b3c9c9f78e9885bcf5;p=linux-beck.git

userns: Convert struct dquot_warn

Convert w_dq_id to be a struct kquid and remove the now unncessary
w_dq_type.

This is a simple conversion and enough other places have already
been converted that this actually reduces the code complexity
by a little bit, when removing now unnecessary type conversions.
