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: split off do_user_path_at_empty from user_path_at_empty() This splits off a new function do_user_path_at_empty from user_path_at_empty that is based on filename and not on a user-specified string. Patch 2: fs: split off setxattr_setup function from setxattr Split off the setup part of the setxattr function. Patch 3: fs: split off do_getxattr from getxattr Split of the do_getxattr part from getxattr. This will allow it to be invoked 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.
