Chao Yu 44a51592ac f2fs: zone: fix to avoid inconsistence in between SIT and SSA [ Upstream commit `773704c1ef` ] w/ below testcase, it will cause inconsistence in between SIT and SSA. create_null_blk 512 2 1024 1024 mkfs.f2fs -m /dev/nullb0 mount /dev/nullb0 /mnt/f2fs/ touch /mnt/f2fs/file f2fs_io pinfile set /mnt/f2fs/file fallocate -l 4GiB /mnt/f2fs/file F2FS-fs (nullb0): Inconsistent segment (0) type [1, 0] in SSA and SIT CPU: 5 UID: 0 PID: 2398 Comm: fallocate Tainted: G O 6.13.0-rc1 #84 Tainted: [O]=OOT_MODULE Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 Call Trace: <TASK> dump_stack_lvl+0xb3/0xd0 dump_stack+0x14/0x20 f2fs_handle_critical_error+0x18c/0x220 [f2fs] f2fs_stop_checkpoint+0x38/0x50 [f2fs] do_garbage_collect+0x674/0x6e0 [f2fs] f2fs_gc_range+0x12b/0x230 [f2fs] f2fs_allocate_pinning_section+0x5c/0x150 [f2fs] f2fs_expand_inode_data+0x1cc/0x3c0 [f2fs] f2fs_fallocate+0x3c3/0x410 [f2fs] vfs_fallocate+0x15f/0x4b0 __x64_sys_fallocate+0x4a/0x80 x64_sys_call+0x15e8/0x1b80 do_syscall_64+0x68/0x130 entry_SYSCALL_64_after_hwframe+0x67/0x6f RIP: 0033:0x7f9dba5197ca F2FS-fs (nullb0): Stopped filesystem due to reason: 4 The reason is f2fs_gc_range() may try to migrate block in curseg, however, its SSA block is not uptodate due to the last summary block data is still in cache of curseg. In this patch, we add a condition in f2fs_gc_range() to check whether section is opened or not, and skip block migration for opened section.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
