add some long-missing capabilities to fs_mask
When POSIX capabilities were introduced during the 2.1 Linux cycle, the fs mask, which represents the capabilities which having fsuid==0 is supposed to grant, did not include CAP_MKNOD and CAP_LINUX_IMMUTABLE. However, before capabilities the privilege to call these did in fact depend upon fsuid==0. This patch introduces those capabilities into the fsmask, restoring the old behavior. See the thread starting at http://lkml.org/lkml/2009/3/11/157 for reference. Note that if this fix is deemed valid, then earlier kernel versions (2.4 and 2.2) ought to be fixed too. Changelog: [Mar 23] Actually delete old CAP_FS_SET definition... [Mar 20] Updated against J. Bruce Fields's patch Reported-by: Igor Zhbanov <izh1979@gmail.com> Signed-off-by: Serge E.
