Those *are* the three commits:
% git log -3 --oneline b34090e
b34090e jbd2: refine waiting for shadow buffers
e5a120a jbd2: remove journal_head from descriptor buffers
f5113ef jbd2: don't create journal_head for temporary journal buffers
Or if you need the full git commit ID's
% git log --pretty=oneline -3 b34090e
b34090e5e22a02fba0e4473056cce9420ad9dd0b jbd2: refine waiting for shadow buffers
e5a120aeb57f40ae568a5ca1dd6ace53d0213582 jbd2: remove journal_head from descriptor buffers
f5113effc2a2ee6b86a4b345ce557353dcbcfffe jbd2: don't create journal_head for temporary journal buffers
Or the URL's:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b34090e5e22a02fba0e4473056cce9420ad9dd0b
