From b698f0a1773f7df73f2bb4bfe0e597ea1bb3881f Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 22 Mar 2022 14:45:38 -0700 Subject: mm/fs: delete PF_SWAPWRITE PF_SWAPWRITE has been redundant since v3.2 commit ee72886d8ed5 ("mm: vmscan: do not writeback filesystem pages in direct reclaim"). Coincidentally, NeilBrown's current patch "remove inode_congested()" deletes may_write_to_inode(), which appeared to be the one function which took notice of PF_SWAPWRITE. But if you study the old logic, and the conditions under which may_write_to_inode() was called, you discover that flag and function have been pointless for a decade.
