Linux kernel source tree

Now that ext4_do_update_inode() return error before filling the whole inode data if we fail to set inode blocks in ext4_inode_blocks_set(). This error should never happen in theory since sb->s_maxbytes should not have allowed this, we have already init sb->s_maxbytes according to this feature in ext4_fill_super(). So even through that could only happen due to the filesystem corruption, we'd better to return after we finish updating the inode because it may left an uninitialized buffer and we could read this buffer later in "errors=continue" mode. This patch make the updating inode data procedure atomic, call EXT4_ERROR_INODE() after we dropping i_raw_lock after something bad happened, make sure that the inode is integrated, and also drop a BUG_ON and do some small cleanups.

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.
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.
