[PATCH 0/4] xfs: Allow user to change project id in un-init userns

[Gao feng <gaofeng@xxxxxxxxxxxxxx>]

This patchset add two helper functions to convert user space project id
to kernel space project id without any struct changed.

Since the projid_map of user namespace has limit the range of valid project
ids for user namespace, we can safely allow user to change file's project
id in un-init user namespace.

Gao feng (4):
  xfs: add helper function to convert project id between user and kernel
    space
  userns: ioctl: convert project id between user and kernel space
  xfs: allow un-init user namespace to change file's project id
  userns: eofblocks: convert project id from user to kernel space
