2008-07-25coda: remove CODA_FS_OLD_APIAdrian Bunk1-14/+0
While fixing CONFIG_ leakages to the userspace kernel headers I ran into CODA_FS_OLD_API. After five years, are there still people using the old API left? Especially considering that you have to choose at compile time which API to support in the kernel (and distributions tend to offer the new API for some time). Jan: "The old API can definitely go. Around the time the new interface went in there were some non-Coda userspace file system implementations that took a while longer to convert to the new API, but by now they all switched to the new interface or in some cases to a FUSE-based solution."

This patch adds config option CONFIG_OCFS2_FS_STATS to allow building the fs with instrumentation enabled.

2008-07-09SUNRPC: Use only rpcbind v2 for AF_INET requestsChuck Lever1-21/+0
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...

2008-04-23NFSD: Remove NFSv4 dependency on NFSv3Chuck Lever1-1/+2
Clean up: Because NFSD_V4 "depends on" NFSD_V3, it appears as a child of the NFSD_V3 menu entry, and is not visible if NFSD_V3 is unselected. 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."

2008-04-23SUNRPC: Remove PROC_FS dependencyChuck Lever1-1/+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>
2008-04-23NFSD: Use "depends on" for PROC_FS dependencyChuck Lever1-2/+1
Recently, commit 440bcc59 added a reverse dependency to fs/Kconfig to ensure that PROC_FS was enabled if NFSD_V4 was enabled. 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.

2008-04-23NFSD: Remove redundant "select" clauses in fs/KconfigChuck Lever1-2/+0
As far as I can tell, selecting the CRYPTO and CRYPTO_MD5 entries under CONFIG_NFSD is redundant, since CONFIG_NFSD_V4 already selects RPCSEC_GSS_KRB5, which selects these entries. Testing with "make menuconfig" shows that the entries under CRYPTO still properly reflect "Y" or "M" based on the setting of CONFIG_NFSD after this change is applied.

Trond and Bruce, This is a patch for 2.6.25. This is the same version that was sent out on December 12 for review (no comments to date). To simplify the RPC/RDMA client and server build configuration, make SUNRPC_XPRT_RDMA a hidden config option that continues to depend on SUNRPC and INFINIBAND. The value of SUNRPC_XPRT_RDMA will be: - N if either SUNRPC or INFINIBAND are N - M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M - Y if both SUNRPC and INFINIBAND are Y In 2.6.25, all of the RPC/RDMA related files are grouped in net/sunrpc/xprtrdma and the net/sunrpc/xprtrdma/Makefile builds both the client and server RPC/RDMA support using this config option.

2008-01-28ext4: Add the journal checksum featureGirish Shilamkar1-0/+1
The journal checksum feature adds two new flags i.e JBD2_FEATURE_INCOMPAT_ASYNC_COMMIT and JBD2_FEATURE_COMPAT_CHECKSUM. JBD2_FEATURE_CHECKSUM flag indicates that the commit block contains the checksum for the blocks described by the descriptor blocks. Due to checksums, writing of the commit record no longer needs to be synchronous. Now commit record can be sent to disk without waiting for descriptor blocks to be written to disk. This behavior is controlled using JBD2_FEATURE_ASYNC_COMMIT flag. Older kernels/e2fsck should not be able to recover the journal with _ASYNC_COMMIT hence it is made incompat. The commit header has been extended to hold the checksum along with the type of the checksum. For recovery in pass scan checksums are verified to ensure the sanity and completeness(in case of _ASYNC_COMMIT) of every transaction.

2008-01-25Preempt-RCU: implementationPaul E. McKenney1-1/+0
This patch implements a new version of RCU which allows its read-side critical sections to be preempted. It uses a set of counter pairs to keep track of the read-side critical sections and flips them when all tasks exit read-side critical section. The details of this implementation can be found in this paper - http://www.rdrop.com/users/paulmck/RCU/OLSrtRCU.2006.08.11a.pdf and the article- http://lwn.net/Articles/253651/ This patch was developed as a part of the -rt kernel development and meant to provide better latencies when read-side critical sections of RCU don't disable preemption. As a consequence of keeping track of RCU readers, the readers have a slight overhead (optimizations in the paper). This implementation co-exists with the "classic" RCU implementations and can be switched to at compiler. Also includes RCU tracing summarized in debugfs.

2007-11-03[CIFS] implement upcalls for SPNEGO blob via keyctl APIJeff Layton1-1/+1
Add routines to handle upcalls to userspace via keyctl for the purpose of getting a SPNEGO blob for a particular uid and server combination. Clean up the Makefile a bit and set it up to only compile cifs_spnego if CONFIG_CIFS_UPCALL is set. Also change CONFIG_CIFS_UPCALL to depend on CONFIG_KEYS rather than CONFIG_CONNECTOR. cifs_spnego.h defines the communications between kernel and userspace and is intended to be shared with userspace programs.
