Hello,
this series cleans up couple of things around debug messages in ext4/jbd2
and removes some unnecessary exports.
Honza
Jbd2 exports jbd2_journal_enable_debug and __jbd2_debug() depite the
first is used only in fs/jbd2/journal.c and the second only within jbd2
code. Remove the pointless exports make jbd2_journal_enable_debug
static.

We use jbd_debug() in some places in ext4. It seems a bit strange to use
jbd2 debugging output function for ext4 code. Also these days
ext4_debug() uses dynamic printk so each debug message can be enabled /
disabled on its own so the time when it made some sense to have these
combined (to allow easier common selecting of messages to report) has
passed. Just convert all jbd_debug() uses in ext4 to ext4_debug().

jbd2_ prefix. Rename jbd_debug() to jbd2_debug(). No functional changes.

jbd2_log_start_commit() is not used outside of jbd2 so unexport it. Also
make __jbd2_log_start_commit() static when we are at it.
