Subject: [PATCH 0/4] ext4: fix incorrect tid assumptions

As discussed here [1], there are a few places in ext4 and jbd2 code where it
is assumed that a tid of '0' is not valid.  Which isn't true.

This small patchset tries to fix (hopefully!) all these places.  Jan Kara
had already identified the functions that needed to be fixed.  I believe
that the only other issue is the handling of sbi->s_fc_ineligible_tid.

Each patch in this series fixes a single function; the last one also fixes
the sbi->s_fc_ineligible_tid handling.
