Subject: [PATCH 0/7] Btrfs: New inode number allocator
Date: Wed, 16 Mar 2011 16:48:55 +0800 [thread overview]
Message-ID: <4D807977.1040506@cn.fujitsu.com> (raw)
Currently btrfs stores the highest objectid of the fs tree, and it always
returns (highest+1) inode number when we create a file, so inode numbers
won't be reclaimed when we delete files, so we'll run out of inode numbers
as we keep create/delete files in 32bit machines.
This patchset aims to fix this, and it works similar to free space caching
for block groups.
I've run xfstests, and I also tested it with snapshot, balance etc.
The patchset is also available in:
