Date: Tue, 23 Oct 2007 14:07:05 -0700 From: Avantika Mathur <mathur@...ux.vnet.ibm.com> To: linux-ext4 <linux-ext4@...r.kernel.org> Subject: Ext4 devel interlock meeting minutes (October 22, 2007) Ext4 Developer Interlock Call October 22, 2007: Meeting Minutes Attendees: Mingming Cao, Andreas Dilger, Eric Sandeen, Dave Kleikamp, Jose Santos, Aneesh Veetil, Valerie Clement, Avantika Mathur - There has been discussion on linux-ext4 about overflow in ext2 with 64 KB block size. Discussed adding an incompat flag to this feature and concluded that it is too late to do this; it will be treated as a bug fix. Patch Status: patches that were not picked up to mainline in the recent pull: - journal_checksum patches - the fsstress kernel oops is not yet resolved, Avantika will be working on this. - i_version: Jean-Noel recently sent out an updated version which adds a lock every time i_version is updated. Still waiting on more review - mballoc - target for next kernel release. Remaining work: - Aneesh plans to run some performance test and include results in the patch description. - Waiting for Alex to address the fixme's that aneesh has added to the code, for more clarification. - block groupdescriptor sync with e2fsprogs: - Aneeesh recently posted patches which have been added to the patch queue. E2fsprogs - Ted has added new branches the the e2fsprogs git tree - master: current stable version - next: patches expected to go into the next stable version - pu: proposed update; patches that are in preliminary review and test phase - E2fsprogs patches should probably be submitted against the 'next' branch of the git tree. - Aneesh was looking for patches to support mke2fs of large filesystems. Valerie's old patches don't apply cleanly. - Documentation in the kernel tree; ext4.txt is out of date and needs to be updated. Performance: - Andreas had asked Chris Mason to add ext4 to his BTRfs benchmarks. Chris Mason reported that ext4 is doing poorly on a test which performs kernel untar and compile on 20 kernels in a row. The performance of ext4 on reads is poor compared to ext3. - Eric will talk to Chris and get all of the details of the tests. - Eric suggested enabling delalloc,mballoc mount options by default. The dellaloc option can then be disabled if the fs is not in writeback journaling mode. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
