Yunlei He cda9cc595f f2fs: report error if quota off error during umount
Now, we depend on fsck to ensure quota file data is ok,
so we scan whole partition if checkpoint without umount
flag. It's same for quota off error case, which may make
quota file data inconsistent.

generic/019 reports below error:

 __quota_error: 1160 callbacks suppressed
 Quota error (device zram1): write_blk: dquota write failed
 Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota
 Quota error (device zram1): write_blk: dquota write failed
 Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota
 Quota error (device zram1): write_blk: dquota write failed
 Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota
 Quota error (device zram1): write_blk: dquota write failed
 Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota
 Quota error (device zram1): write_blk: dquota write failed
 Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota
 VFS: Busy inodes after unmount of zram1. Self-destruct in 5 seconds.  Have a nice day...

If we failed in below path due to fail to write dquot block, we will miss
to release quota inode, fix it.

- f2fs_put_super
 - f2fs_quota_off_umount
  - f2fs_quota_off
   - f2fs_quota_sync   <-- failed
   - dquot_quota_off   <-- missed to call

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
