void ext3_init_block_alloc_info ( struct inode * inode )

ext3_init_block_alloc_info() : file inode structure

Allocate and initialize the reservation window structure, and link the window to the ext3 inode structure at last

The reservation window structure is only dynamically allocated and linked to ext3 inode the first time the open file needs a new block. So, before every ext3_new_block(s) call, for regular files, we should check whether the reservation window structure exists or not. In the latter case, this function is called. Fail to do so will result in block reservation being turned off for that open file.

This function is called from ext3_get_blocks_handle(), also called when setting the reservation window size through ioctl before the file is open for write (needs block allocation).

Needs truncate_mutex protection prior to call this function.
