With below testcase, we will fail to find existed xattr entry: 1. mkfs.f2fs -O extra_attr -O flexible_inline_xattr /dev/zram0 2. mount -t f2fs -o inline_xattr_size=1 /dev/zram0 /mnt/f2fs/ 3. touch /mnt/f2fs/file 4. setfattr -n "user.name" -v 0 /mnt/f2fs/file 5. getfattr -n "user.name" /mnt/f2fs/file /mnt/f2fs/file: user.name: No such attribute The reason is for inode which has very small inline xattr size, __find_inline_xattr() will fail to traverse any entry due to first entry may not be loaded from xattr node yet, later, we may skip to check entire xattr datas in __find_xattr(), result in such wrong condition. This patch adds condition to check such case to avoid this issue. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

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.
