| H A D | inode.c | c2b513df Tue Oct 04 11:48:44 CDT 2005 Al Viro <viro@ftp.linux.org.uk> [PATCH] bfs iget() abuses
bfs_fill_super() walks the inode table to get the bitmap of free inodes
and collect stats. It has no business using iget() for that - it's a
lot of extra work, extra icache pollution and more complex code.
Switched to walking the damn thing directly.
Note: that also allows to kill ->i_dsk_ino in there - separate patch if
Tigran can confirm that this field can be zero only for deleted inodes
(i.e. something that could only be found during that scan and not by
normal lookups).
