linux.git/fs/ceph, branch v2.6.39 Linux kernel source tree ceph: do not use i_wrbuffer_ref as refcount for Fb cap 2011-05-11T17:44:48+00:00 Henry C Chang henry.cy.chang@gmail.com 2011-05-11T10:29:54+00:00 d3d0720d4a7a46e93e055e5b0f1a8bd612743ed6 We increments i_wrbuffer_ref when taking the Fb cap. This breaks the dirty page accounting and causes looping in __ceph_do_pending_vmtruncate, and ceph client hangs. This bug can be reproduced occasionally by running blogbench. Add a new field i_wb_ref to inode and dedicate it to Fb reference counting. Signed-off-by: Henry C Chang <henry.cy.chang@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net> 
We increments i_wrbuffer_ref when taking the Fb cap. This breaks
the dirty page accounting and causes looping in
__ceph_do_pending_vmtruncate, and ceph client hangs.

This bug can be reproduced occasionally by running blogbench.

Add a new field i_wb_ref to inode and dedicate it to Fb reference
counting.
