The patch titled
ufs: fix truncated values handling 64 bit metadata
has been removed from the -mm tree. Its filename was
ufs-truncated-values-handling-64-bit-metadata.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: ufs: fix truncated values handling 64 bit metadata
From: Dan Carpenter <error27@xxxxxxxxx>
Originally i_lastfrag was 32 bits but then we added support for handling
64 bit metadata and it became a 64 bit variable. That was during 2007, in
54fb996ac15c "[PATCH] ufs2 write: block allocation update". Unfortunately
these casts got left behind so the value got truncated to 32 bit again.
[akpm@xxxxxxxxxxxxxxxxxxxx: remove now-unneeded min_t/max_t casting]
