答复: [RFC PATCH] ext4: add link file support for {GET,SET}XATTR ioctl

[Wang Shilong <wshilong@xxxxxxx>]

Hi Dave, Darrick,

      Thanks for good suggestions!
As my understanding, we could modify 

do_fchownat() to change project ID instead of
group id if AT_FCHOWN_PROJID(new flags) passed in.

Besides that we also need a new flag AT_FCHOWN_PROJ_INHERIT.
to set/clear inherit attributes? 

And for Project Get, we might need extend 'struct attr {'
to include project id.

What do you think?

Thanks,
Shilong
