[U-Boot] [PATCH v3 1/1] fs: fat/ext4/sandbox: Deal with files > 2GB
Suriyan Ramasami
suriyan.r at gmail.com
Mon Oct 27 05:42:52 CET 2014
The commands fatls/ext4ls give -ve values when dealing with files > 2GB.
The commands fatsize/ext4size do not update the variable filesize for
these files.
To deal with this, the functions have been modified to take an additional
parameter of type "* loff_t" which is then populated. The return value of the
functions are solely used for error contitions.

v3:
* Added testcase to test writes
* Correct function set_contents() in fs/fat/fat_write.c
v2:
* Added test case for fat/ext4 in test/fs/testfs.sh
* md5sum: call map_sysmem() for buffer that md5_wd will work on
v1:
* First try.
