This adds the xattr support to io_uring. 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.
