xfs_check out of memory

[Leo Qiu <leo.qiu@xxxxxxxxx>]

Hi, I am using xfs_check (version 2.6.25)  for my 760MB xfs file
system and get an out of memory error.
I looked through the source code and found that in init() function in
the check.c, it tries to allocate many big buffers for inomap and
dbmap for each allocation group.

In my case, it tries to allocate about  about 6MB for dbmap and 24MB
for inomap for each of my 32 allocation groups. After 30 rounds of
that, the program complains the memory problem.

Has anyone seen the simliar issue?

Thank you.

Leo
