This is done because we want to avoid bugs in the future\nwhere we check for only effective fsuid of the current task against a\nfile\u0027s owning uid, without simultaneously checking for CAP_FOWNER as\nwell, thus violating its semantics.\n[ XFS uses special macros and structures, and in general looked ...\nuntouchable, so we leave it alone -- but it has been looked over. ]\n\nThe (current-\u003efsuid !\u003d inode-\u003ei_uid) check in generic_permission() and\nexec_permission_lite() is left alone, because those operations are\ncovered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations\nfalling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.\n\nSigned-off-by: Satyam Sharma \u003cssatyam@cse.iitk.ac.in\u003e\nCc: Al Viro \u003cviro@ftp.linux.org.uk\u003e\nAcked-by: Serge E.
