Subject: [PATCH 0/8] add generic interface to set/get project

From: Wang Shilong <wshilong@....com>

Currently, Filesystem use FS_IOC_FS_SETXATTR ioctl
to change project ID of file. However we don't
support ioctl on symlink files, and it is desirable
to change symlink files' project ID just like uid/gid.

This patch try to reuse existed interface fchownat(),
use group id to set project ID if flag AT_FCHOWN_PROJID
passed in.

Also extend statx() calles to get symlink files' project
ID and inherit attribute.

Wang Shilong (8):
  fs: add support to change project ID
  ext4: support project ID in ext4_setattr()
  f2fs: support project ID in f2fs_setattr()
  xfs: support project ID in xfs_setattr()
  fs: add project support to statx
  ext4: support project in ext4_getattr()
  f2fs: support project in f2fs_getattr()
  xfs: support project in xfs_getattr()
