| | * | Btrfs: Add zlib compression supportChris Mason2008-10-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a large change for adding compression on reading and writing, both for inline and regular extents. It does some fairly large surgery to the writeback paths. Compression is off by default and enabled by mount -o compress. Even when the -o compress mount option is not used, it is possible to read compressed extents off the disk. If compression for a given set of pages fails to make them smaller, the file is flagged to avoid future compression attempts later. * While finding delalloc extents, the pages are locked before being sent down to the delalloc handler. This allows the delalloc handler to do complex things such as cleaning the pages, marking them writeback and starting IO on their behalf. * Inline extents are inserted at delalloc time now. This allows us to compress the data before inserting the inline extent, and it allows us to insert an inline extent that spans multiple pages. * All of the in-memory extent representations (extent_map.c, ordered-data.c etc) are changed to record both an in-memory size and an on disk size, as well as a flag for compression. From a disk format point of view, the extent pointers in the file are changed to record the on disk size of a given extent and some encoding flags. Space in the disk format is allocated for compression encoding, as well as encryption and a generic 'other' field. Neither the encryption or the 'other' field are currently used. In order to limit the amount of data read for a single random read in the file, the size of a compressed extent is limited to 128k. This is a software only limit, the disk format supports u64 sized compressed extents. In order to limit the ram consumed while processing extents, the uncompressed size of a compressed extent is limited to 256k. This is a software only limit and will be subject to tuning later. Checksumming is still done on compressed extents, and it is done on the uncompressed version of the data. This way additional encodings can be layered on without having to figure out which encoding to checksum. Compression happens at delalloc time, which is basically singled threaded because it is usually done by a single pdflush thread. This makes it tricky to spread the compression load across all the cpus on the box. We'll have to look at parallel pdflush walks of dirty inodes at a later time. Decompression is hooked into readpages and it does spread across CPUs nicely. Signed-off-by: Chris Mason <chris.mason@oracle.com>

That's not a common issue, but I just ran into it and since there's no reason to get a built-in mbcache in this case this patch fixes it.

It's a pretty trivial change. Most functions are just renamed. The only functional change is moving to Jan's inode-based ordered data mode. It's better, too. Because JBD2 reads and writes JBD journals, this is compatible with any existing filesystem. It can even interact with JBD-based ocfs2 as long as the journal is formated for JBD. We provide a compatibility option so that paranoid people can still use JBD for the time being. This will go away shortly.

A new kernel build option allows distributions to use the legacy v2 call until they integrate an appropriate user-space rpcbind daemon that can support IPv6 RPC services. I tried adding some automatic logic to fall back if registering with a v4 protocol request failed, but there are too many corner cases. So I just made it a compile-time switch that distributions can throw when they've replaced portmapper with rpcbind. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some server vendors support the higher versions of rpcbind only for AF_INET6. The kernel doesn't need to use v3 or v4 for AF_INET anyway, so change the kernel's rpcbind client to query AF_INET servers over rpcbind v2 only. This has a few interesting benefits: 1. If the rpcbind request is going over TCP, and the server doesn't support rpcbind versions 3 or 4, the client reduces by two the number of ephemeral ports left in TIME_WAIT for each rpcbind request. This will help during NFS mount storms. 2. The rpcbind interaction with servers that don't support rpcbind versions 3 or 4 will use less network traffic. Also helpful during mount storms. 3. We can eliminate the kernel build option that controls whether the kernel's rpcbind client uses rpcbind version 3 and 4 for AF_INET servers. Less complicated kernel configuration...

Shared (large) page tables are implemented in software emulation mode, by using page->index of the first tail page from a compound large page to store page table information.

Replace the dependency on NFSD_V3 with a "select NFSD_V3". This makes NFSD_V4 look and work just like NFS_V3, while ensuring that NFSD_V3 is enabled if NFSD_V4 is. Sam Ravnborg adds: "This use of select is questionable. In general it is bad to select a symbol with dependencies. In this case the dependencies of NFSD_V3 are duplicated for NFSD_V4 so we will not se erratic configurations but do you remember to update NFSD_V4 when you add a depends on NFSD_V3? But I see no other clean way to do it right now." Later he said: "My comment was more to say we have things to address in kconfig. This is abuse in the acceptable range."

* | | SUNRPC: Remove PROC_FS dependencyChuck Lever2008-04-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, commit 440bcc59 added a reverse dependency to fs/Kconfig to ensure that PROC_FS was enabled if SUNRPC_GSS was enabled. Apparently this isn't necessary because the auth_gss components under net/sunrpc will build correctly even if PROC_FS is disabled, though RPCSEC_GSS will not work without /proc. It also violates the guideline in Documentation/kbuild/kconfig-language.txt that states "In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies." To address these issues, remove the dependency. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

There is a guideline in Documentation/kbuild/kconfig-language.txt that states "In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies." A quick grep around other Kconfig files reveals that no entry currently uses "select PROC_FS" -- every one uses "depends on". Thus CONFIG_NFSD_V4 should use "depends on PROC_FS" as well.
