The intent is to have a more complete support for file operations in io_uring. This change adds support for the following functions to io_uring: - fgetxattr - fsetxattr - getxattr - setxattr Patch 1: fs: make user_path_at_empty() take a struct filename The user_path_at_empty filename parameter has been changed from a const char user pointer to a filename struct. io_uring operates on filenames. In addition also the functions that call user_path_at_empty in namei.c and stat.c have been modified for this change. Patch 2: fs: split off setxattr_setup function from setxattr Split off the setup part of the setxattr function Patch 3: fs: split off the vfs_getxattr from getxattr Split of the vfs_getxattr part from getxattr. This will allow to invoke it from io_uring. Patch 4: io_uring: add fsetxattr and setxattr support This adds new functions to support the fsetxattr and setxattr functions. Patch 5: io_uring: add fgetxattr and getxattr support This adds new functions to support the fgetxattr and getxattr functions. There are two additional patches: liburing: Add support for xattr api's. This also includes the tests for the new code. xfstests: Add support for io_uring xattr support.
