[PATCH v1 0/5] io_uring: add xattr support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
