[PATCH] xfs: Drop setting redundant PF_KSWAPD in kswapd context

From: Anshuman Khandual
Date: Thu Aug 24 2017 - 06:43:05 EST


xfs_btree_split() calls xfs_btree_split_worker() with args.kswapd set
if current->flags alrady has PF_KSWAPD. Hence we should not again add
PF_KSWAPD into the current flags inside kswapd context. So drop this
redundant flag addition.
