Subject: [PATCH] xfs: reduce stack usage in xfs_bmap_btalloc()
Date: Saturday, April 26, 2008 - 10:51 am

Hi David,

This patch reduces xfs_bmap_btalloc() stack usage by 50 bytes
by moving part of its body into a helper function.

This results in some variables not taking stack space in
xfs_bmap_btalloc() anymore.

The helper itself does not call anything stack-deep.
Stack-deep call to xfs_alloc_vextent() happen
in xfs_bmap_btalloc(), as before.

Compile tested only.
