Date: Wed, 08 Jul 2009 14:33:00 -0000 [thread overview] Message-ID: <20090708143318.21839.qmail@sourceware.org> (raw) CVSROOT: /cvs/lvm2 Module name: LVM2 Changes by: wysochanski@sourceware.org 2009-07-08 14:33:17 Modified files: lib/metadata : metadata-exported.h metadata.c tools : vgextend.c vgmerge.c vgreduce.c vgremove.c vgsplit.c Log message: Remove unneeded LOCK_NONBLOCKING from vg_read() API. Remove unneeded LOCK_NONBLOCKING from vg_read() API and tools that use it. We no longer need this flag anywhere since we now automatically set LCK_NONBLOCK inside lock_vol() if vgs_locked(). For further details, see: commit d52b3fd3fe2006e2d13e42f8518b6512bff03710 Author: Dave Wysochanski <dwysocha@redhat.com> Date: Wed May 13 13:02:52 2009 +0000 Remove NON_BLOCKING lock flag from tools and set a policy to auto-set. As a simplification to the tools and further liblvm, this patch pushes the setting of NON_BLOCKING lock flag inside the lock_vol() call. The policy we set is if any existing VGs are currently locked, we set the NON_BLOCKING flag. At some point it may make sense to add this flag back if we get an RFE from a liblvm user, but for now let's keep it as simple as possible.
