[Gluster-users] is this fix included in glusterfs3.4.2-1 ?

[Khoi Mai]

Hi community,

Can you tell me if the hugepages fix glusterfs-3.4.0.33rhs-1 package is 
incorporated in the glusterfs-3.4.2-1 package?  I believe I had 
experienced a 'locking' scenario within 1 of my FUSE mounts.  I didn't get 
functionality back until I forced unmounted a particular volume 
(distri-rep volume 2 x 4 =8).  In dmesg I did have a stack trace.  I 
currently do not have hugepages turned off because I was unaware that it 
was enabled on rhel6 by default.
