From: Wang Shilong <wshilong@xxxxxxx> 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() fs/attr.c | 26 +++++++++++++-- fs/ext4/inode.c | 15 +++++++-- fs/f2fs/file.c | 12 +++++-- fs/open.c | 29 +++++++++++++---- fs/quota/dquot.c | 23 ++++++++++++++ fs/stat.c | 1 + fs/xfs/xfs_iops.c | 54 ++++++++++++++++++++++++++------ fs/xfs/xfs_linux.h | 10 ++++++ include/linux/fs.h | 3 ++ include/linux/quotaops.h | 9 ++++++ include/linux/stat.h | 2 ++ include/uapi/linux/fcntl.h | 1 + include/uapi/linux/stat.h | 8 +++-- tools/include/uapi/linux/fcntl.h | 1 + tools/include/uapi/linux/stat.h | 8 +++-- 15 files changed, 175 insertions(+), 27 deletions(-) -- 2.19.1
