Date: Fri, 22 Feb 2008 12:35:14 -0800 From: Mingming Cao <cmm@...ibm.com> To: linux-ext4@...r.kernel.org, Alex Tomas <bzzz.tomas@...il.com> Subject: [RFC] Delayed allocation updates Hi, ext4 patch queue has keeping a set of delayed allocation for a while. The know todo is add reservation and ordered mode support. FYI, The base delayed allocation patches are located at VFS changes: http://repo.or.cz/w/ext4-patch-queue.git?a=blob;f=delalloc-vfs.patch;h=713004ca3f01ae9e7ace289c596ce25901b6c28a;hb=dc9fa932e786df0f2e18402e990926be667484ac ext4 support: http://repo.or.cz/w/ext4-patch-queue.git?a=blob;f=delalloc-ext4.patch;h=67f8e2802f52e52497a9a8360a1d979bc60c2142;hb=dc9fa932e786df0f2e18402e990926be667484ac Here is the updates to the delayed allocation patches in the ext4 patch queue. - update delayed allocation with current VFS API write_begin/write_end - general handling preallocation - add block reservation to handle ENOSPC error Patches will follow. compiles, plan to add to the patch later. Comments? I looked at ordered mode briefly but not entirely clear how that could be done without a new callback function. Perhaps Alex has some thoughts?
