Subject: [f2fs-dev] [Bug 218096] New: first 4K all zeros when release_cblocks set, reserve_cblocks restores access
Date: Fri, 03 Nov 2023 06:26:04 +0000 [thread overview]
Message-ID: <bug-218096-202145@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=218096
Bug ID: 218096
Summary: first 4K all zeros when release_cblocks set,
reserve_cblocks restores access
Product: File System
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: f2fs
Assignee: filesystem_f2fs@kernel-bugs.kernel.org
Reporter: slandden@gmail.com
Regression: No
Using 6.1.51 on armv7 when I release compressed blocks then the first page I
read from a file on the F2FS filesystem is all zeros.
f2fs_io release_cblocks <FILE>
hd <FILE> | head
(first 4K is all zero)
f2fs_io reserve_cblocks <FILE>
hd <FILE> | head
(first 4K now reads correctly)
I am having trouble reproducing this in a virtual machine however. This machine
has 3.5G/4G if that is somehow relevant.
