2006-03-27[PATCH] knfsd: Break the hard linkage from svc_expkey to svc_exportNeilBrown
Current svc_expkey holds a pointer to the svc_export structure, so updates to that structure have to be in-place, which is a wart on the whole cache infrastruct. So we break that linkage and just do a second lookup. If this became a performance issue, it would be possible to put a direct link back in which was only used conditionally. i.e. when an object is replaced in the cache, we set a flag in the old object. When dereferencing the link from svc_expkey, if the flag is set, we drop the reference and do a fresh lookup.

2006-03-27[PATCH] autofs4: nameidata needs to be up to date for follow_linkIan Kent
In order to be able to trigger a mount using the follow_link inode method the nameidata struct that is passed in needs to have the vfsmount of the autofs trigger not its parent. During a path walk if an autofs trigger is mounted on a dentry, when the follow_link method is called, the nameidata struct contains the vfsmount and mountpoint dentry of the parent mount while the dentry that is passed in is the root of the autofs trigger mount. I believe it is impossible to get the vfsmount of the trigger mount, within the follow_link method, when only the parent vfsmount and the root dentry of the trigger mount are known. This patch updates the nameidata struct on entry to __do_follow_link if it detects that it is out of date. It moves the path_to_nameidata to above __do_follow_link to facilitate calling it from there. The dput_path is moved as well as that seemed sensible. No changes are made to these two functions.

2006-03-27[PATCH] autofs4: expire mounts that hold no (extra) references onlyIan Kent
Alter the expire semantics that define how "busyness" is determined. Currently a last_used counter is updated on every revalidate from processes other than the mount owner process group. This patch changes that so that an expire candidate is busy only if it has a reference count greater than the expected minimum, such as when there is an open file or working directory in use. This method is the only way that busyness can be established for direct mounts within the new implementation. For consistency the expire semantic is made the same for all mounts. A side effect of the patch is that mounts which remain mounted unessessarily in the presence of some GUI programs that scan the filesystem should now expire.

2006-03-27[PATCH] autofs4: fix false negative return from expireIan Kent
Fix the case where an expire returns busy on a tree mount when it is in fact not busy. This case was overlooked when the patch to prevent the expiring away of "scaffolding" directories for tree mounts was applied. The problem arises when a tree of mounts is a member of a map with other keys. The current logic will not expire the tree if any other mount in the map is busy. The solution is to maintain a "minimum" use count for each autofs dentry and compare this to the actual dentry usage count during expire.

2006-03-27[PATCH] autofs4: can't mount due to mount point dir not emptyIan Kent
Addresse a problem where stale dentrys stop mounts from happening. When a mount point directory is pre-created and a non-existent entry within it is requested a dentry ends up being created within the mount point directory which stops future mounts. The problem is solved by ignoring negative, unhashed dentrys in the mount point d_subdirs list. Additionally the apparent cacheing of -ENOENT returns from requests is removed. The test on d_time is a tautology and d_time is not initialised and has an unexpected value. In short it doesn't do what it's meant to. The cacheing of failed requests to the daemon is important and will be followed up later.

2006-03-26[PATCH] ext3_get_blocks: Adjust reservation window size for mblocksMingming Cao
Optimize the block reservation and the multiple block allocation: with the knowledge of the total number of blocks ahead, set or adjust the reservation window size properly (based on the number of blocks needed) before block allocation happens: if there isn't any reservation yet, make sure the reservation window equals to or greater than the number of blocks needed, before create an reservation window; if a reservation window is already exists, try to extends the window size to match the number of blocks to allocate. This could increase the possibility of completing multiple blocks allocation in a single request, as blocks are only allocated in the range of the inode's reservation window.

2006-03-26[PATCH] ext3_get_blocks: Mapping multiple blocks at a onceMingming Cao
Currently ext3_get_block() only maps or allocates one block at a time. This is quite inefficient for sequential IO workload. I have posted a early implements a simply multiple block map and allocation with current ext3. The basic idea is allocating the 1st block in the existing way, and attempting to allocate the next adjacent blocks on a best effort basis. More description about the implementation could be found here: http://marc.theaimsgroup.com/?l=ext2-devel&m=112162230003522&w=2 The following the latest version of the patch: break the original patch into 5 patches, re-worked some logicals, and fixed some bugs. The break ups are: [patch 1] Adding map multiple blocks at a time in ext3_get_blocks() [patch 2] Extend ext3_get_blocks() to support multiple block allocation [patch 3] Implement multiple block allocation in ext3-try-to-allocate (called via ext3_new_block()). [patch 4] Proper accounting updates in ext3_new_blocks() [patch 5] Adjust reservation window size properly (by the given number of blocks to allocate) before block allocation to increase the possibility of allocating multiple blocks in a single call. Tests done so far includes fsx,tiobench and dbench. The following numbers collected from Direct IO tests (1G file creation/read) shows the system time have been greatly reduced (more than 50% on my 8 cpu system) with the patches. 1G file DIO write: 2.6.15 2.6.15+patches real 0m31.275s 0m31.161s user 0m0.000s 0m0.000s sys 0m3.384s 0m0.564s 1G file DIO read: 2.6.15 2.6.15+patches real 0m30.733s 0m30.624s user 0m0.000s 0m0.004s sys 0m0.748s 0m0.380s Some previous test we did on buffered IO with using multiple blocks allocation and delayed allocation shows noticeable improvement on throughput and system time. This patch: Add support of mapping multiple blocks in one call. This is useful for DIO reads and re-writes (where blocks are already allocated), also is in line with Christoph's proposal of using getblocks() in mpage_readpage() or mpage_readpages().
