[ Upstream commit622927f3b8] With below mkfs and mount option: MKFS_OPTIONS -- -O extra_attr -O project_quota -O inode_checksum -O flexible_inline_xattr -O inode_crtime -f MOUNT_OPTIONS -- -o noinline_xattr We may miss xattr data with below testcase: - mkdir dir - setfattr -n "user.name" -v 0 dir - for ((i = 0; i < 190; i++)) do touch dir/$i; done - umount - mount - getfattr -n "user.name" dir user.name: No such attribute The root cause is that we persist xattr data into reserved inline xattr space, even if inline_xattr is not enable in inline directory inode, after inline dentry conversion, reserved space no longer exists, so that xattr data missed. Let's use inline xattr space only if inline_xattr flag is set on inode to fix this iusse.

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.
