gfs2: Add common helper for holding and releasing the freeze glock
[ Upstream commit c77b52c0a137994ad796f44544c802b0b766e496 ]
Many places in the gfs2 code queued and dequeued the freeze glock.
Almost all of them acquire it in SHARED mode, and need to specify the
same LM_FLAG_NOEXP and GL_EXACT flags.
This patch adds common helper functions gfs2_freeze_lock and gfs2_freeze_unlock
to make the code more readable, and to prepare for the next patch.
