[r8905] made the following change on the 2.6 branch:

as a preparation to fix a race condition about privilege in libgfarm/gfsl, move privilege lock / unlock functions from libgfarm/gfarm to libgfarm/gfutil, and rename them from gfarm_authprivilege() to gfarmprivilege().

[r8909] fixed race conditions about privileges in libgfarm/gfsl, and [r8910] removed gss_mutex, because it became unnecessary after [r8909]. the latter is pointed out by tatebe@-san. both changes have been only committed on the 2.6 branch.
