David Anderson 83782a6877 AOSP: e2fsdroid: Don't over-reserve blocks for files in Base FS. 
If a large number of blocks move from one file to another file,
e2fsdroid will inadvertently reserve the moved blocks for the source
file. If the larger file is visited first, it can fail to acquire blocks
because they're reserved by the smaller file.

This patch only reserves the first N blocks of a file in Base FS, where N
is large enough to satisfy the |st_size| property from lstat(2). We only
consider "owned" blocks rather than deduplicated blocks, in case the new
file cannot be deduplicated.

Test: e2fsdroid with dynamic partitions

README 

	This is the new version (1.46.2) of the second extended file
system management programs.

	From time to time, I release new versions of e2fsprogs, to fix
bugs and to make the utilities more robust.  You can always find
information about the latest version at the the e2fsprogs web page,
which is:

	http://e2fsprogs.sourceforge.net

	The INSTALL file has instructions on building and installing
e2fsprogs.  Provisions for building Red Hat RPMs and Debian dpkg files
are supplied as well.

	In case of bugs in these programs, please contact Ted Ts'o at
tytso@mit.edu or tytso@alum.mit.edu.  See the e2fsck man page for
suggestions of what sort of information to include when submitting bug
reports for these programs.
