Subject: um, exec: remove redundant set_fs(USER_DS)
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=c0ce5b673457123406f19e616bb8cf20a0c12cb5;p=~shefty%2Frdma-dev.git

um, exec: remove redundant set_fs(USER_DS)

The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.
