Subject: [PATCH 0/2] tests/ext4: Ensure resizes with sparse_super2 are handled correctly
Date: Mon, 7 Feb 2022 13:55:32 +0530 [thread overview]
Message-ID: <cover.1644217569.git.ojaswin@linux.ibm.com> (raw)
As detailed in the patch [1], kernel currently does not support resizes
with sparse_super2 enabled. Before the above patch, if we used the
EXT4_IOC_RESIZE_FS ioctl directly, wiht sparse_super2 enabled, the
kernel used to still try the resize and ultimatley leave the fs in an
inconsistent state. This also led to corruption and kernel BUGs.
This patchset adds a test for ext4 to ensure that the kernel handles
resizes with sparse_super2 correctly, and returns -EOPNOTSUPP.
Summary:
Patch 1: Fix the src/ext4_resize.c script to return accurate error codes.
Patch 2: Add the ext4 test for checking resize functionality
