2014-09-11staging/lustre: remove lvfs.hJohn L. Hammond1-1/+1
Move the definition of struct lvfs_run_ctxt to the one file that needed it (lustre/include/obd.h). Remove the then unneeded headers lustre/include/lvfs.h and lustre/include/linux/lvfs.h.

2014-08-17staging/lustre/ldlm: drop redundant ibits lock interoperability checkFan Yong1-0/+1
In very old release (older than Lustre-1.8), if the client talks with the server that does not support ibits lock, then the client needs to convert it as plain lock. Such interoperability check and convertion is out of date for a long time. Drop it.

Don't rely on a "custom" LPROCFS define, it's not needed, just check for the real thing. This will let us delete a whole .h file that is not being used for anything other than one #define.

In drivers/staging/lustre/lustre/include there was a bunch of .h files relying on ccflags to be set up right. Make all of them proper relative paths so that ccflags for different subdirs can be now removed.

2014-07-11staging: lustre: remove top level ccflags variableGreg Kroah-Hartman1-1/+1
We need to remove the ccflags from the Lustre code as it prevents individual object files from building properly in the kernel build system. It also hids the horrid mess that the Lustre include files are made up of. Start out by removing the toplevel ccflags variable pointing to drivers/staging/lustre/include/ as a valid include path. This requires the absolute include markings of a bunch of .h and .c files, which is also done here.

2014-04-27staging/lustre: restore __GFP_WAIT flag to memalloc callsAnn Koehler1-5/+5
In Lustre 2.4, the flags passed to the memory allocation functions are translated from CFS enumeration values types to the kernel GFP values by calling cfs_alloc_flags_to_gfp(). This function adds __GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx. This means that most memory allocation calls are missing the __GFP_WAIT flag. The result is that Lustre experiences more ENOMEM errors, many of which the higher levels of Lustre do not handle robustly. Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces __GFP_IO with GFP_NOFS. Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in Lustre 2.4 so it has never been used with __GFP_WAIT.

This patch implements an extended attribute cache for a Lustre client. It is organized as a write-through cache: reads are performed from cache, updates are sent synchronously to the MDS. An additional inode bit MDS_INODELOCK_XATTR is added to protect the cache.

Lustre is the most deployed distributed file system in the HPC (High Performance Computing) world. The patch adds its client side support. The code is not very clean and needs to live in drivers/staging for some time for continuing cleanup work. See drivers/staging/lustre/TODO for details.
