From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Return-Path: From: Amir Goldstein Subject: [PATCH] fstests: Check that high-offset reads and writes work on non-blockdev fs Date: Tue, 5 Feb 2019 21:42:02 +0200 Message-Id: <20190205194202.31745-1-amir73il@gmail.com> To: Eryu Guan Cc: Miklos Szeredi , "Darrick J . Wong" , linux-unionfs@vger.kernel.org, fstests@vger.kernel.org List-ID: This is a variant of test generic/466 for filesystems that do not support mkfs_sized It is needed for testing high-offset reads and writes with overlayfs over a basefs that supports huge files. Signed-off-by: Amir Goldstein --- Eryu, This test found some issues with WIP implementation of overlayfs page cache. I though of extending generic/466 to test also with "default" block size, but turned out to be simpler and cleaner to fork the test.
