This commit preserves the recursive function dbuf_hold_impl() but moves the local variables and function arguments to the heap to minimize the stack frame size. Enough space is initially allocated on the stack for 20 levels of recursion. This technique was based on commit 34229a2f2ac07363f64ddd63e014964fff2f0671 which reduced stack usage of traverse_visitbp(). Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
Documentation for building, configuring, and using ZFS can be found at: http://wiki.github.com/behlendorf/zfs/
