Subject: [PATCH 0/2 v2] Fix deadlock with suspend & quotas


  Hello Al,

  This is my attempt to fix deadlock in quota code when filesystem is
suspended and someone tries to modify quota e.g. via Q_SETQUOTA command. I
added a VFS function to get a superblock reference and return only after
the filesystem is thawed.

Changes since v1:
* wait for frozen fs really only when requested
* updated some comments & names
