3 | Subject: ocfs2: add ocfs2_xattr_set_handle | |
4 | Patch-mainline: 2.6.29 | |
5 | ||
6 | This function is used to set xattr's in a started transaction. It is only | |
7 | called during inode creation inode for initial security/acl xattrs of the | |
8 | new inode. These xattrs could be put into ibody or extent block, so xattr | |
9 | bucket would not be use in this case. | |
