[ Upstream commit cda9cc595f ]
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

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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
