From 848dd6fba652588597740805730137f17464485c Mon Sep 17 00:00:00 2001 From: Wei Gao via ltp Date: Wed, 24 Jan 2024 19:47:32 -0500 Subject: [PATCH] fs_fill: Increase test loop device size to 1GB On PPC64 the page size is 64K and this causes trouble on btrfs filesystems of small size (LTP currently uses 300M), the threads could compete for a very small number of pages/blocks to actually write the data. So increase minimal device size to 1G avoid the corner case.
