From 622daaff0a8975fb5c5b95f24f3234550ba32e92 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sun, 26 Dec 2010 16:38:43 +0900 Subject: nilfs2: fiemap support This adds fiemap to nilfs. Two new functions, nilfs_fiemap and nilfs_find_uncommitted_extent are added. nilfs_fiemap() implements the fiemap inode operation, and nilfs_find_uncommitted_extent() helps to get a range of data blocks whose physical location has not been determined. nilfs_fiemap() collects extent information by looping through nilfs_bmap_lookup_contig and nilfs_find_uncommitted_extent routines.
