2021-06-02xfs: push perags through the ag reservation calloutsDave Chinner7-23/+23
We currently pass an agno from the AG reservation functions to the individual feature accounting functions, which in future may have to do perag lookups to access per-AG state. Instead, pre-emptively plumb the perag through from the highest AG reservation layer to the feature callouts so they won't have to look it up again.

2021-06-02xfs: prepare for moving perag definitions and support to libxfsDave Chinner2-33/+42
The perag structures really need to be defined with the rest of the AG support infrastructure. The struct xfs_perag and init/teardown has been placed in xfs_mount.[ch] because there are differences in the structure between kernel and userspace. Mainly that userspace doesn't have a lot of the internal stuff that the kernel has for caches and discard and other such structures. However, it makes more sense to move this to libxfs than to keep this separation because we are now moving to use struct perags everywhere in the code instead of passing raw agnumber_t values about. Hence we shoudl really move the support infrastructure to libxfs/xfs_ag.[ch]. To do this without breaking userspace, first we need to rearrange the structures and code so that all the kernel specific code is located together. This makes it simple for userspace to ifdef out the all the parts it does not need, minimising the code differences between kernel and userspace. The next commit will do the move...

2021-06-01xfs: Add delay ready attr set routinesAllison Henderson5-220/+610
This patch modifies the attr set routines to be delay ready. This means they no longer roll or commit transactions, but instead return -EAGAIN to have the calling routine roll and refresh the transaction. In this series, xfs_attr_set_args has become xfs_attr_set_iter, which uses a state machine like switch to keep track of where it was when EAGAIN was returned. See xfs_attr.h for a more detailed diagram of the states. Two new helper functions have been added: xfs_attr_rmtval_find_space and xfs_attr_rmtval_set_blk. They provide a subset of logic similar to xfs_attr_rmtval_set, but they store the current block in the delay attr context to allow the caller to roll the transaction between allocations. This helps to simplify and consolidate code used by xfs_attr_leaf_addname and xfs_attr_node_addname. xfs_attr_set_args has now become a simple loop to refresh the transaction until the operation is completed. Lastly, xfs_attr_rmtval_remove is no longer used, and is removed.

2021-06-01xfs: Add delay ready attr remove routinesAllison Henderson6-86/+327
This patch modifies the attr remove routines to be delay ready. This means they no longer roll or commit transactions, but instead return -EAGAIN to have the calling routine roll and refresh the transaction. In this series, xfs_attr_remove_args is merged with xfs_attr_node_removename become a new function, xfs_attr_remove_iter. This new version uses a sort of state machine like switch to keep track of where it was when EAGAIN was returned. A new version of xfs_attr_remove_args consists of a simple loop to refresh the transaction until the operation is completed. A new XFS_DAC_DEFER_FINISH flag is used to finish the transaction where ever the existing code used to. Calls to xfs_attr_rmtval_remove are replaced with the delay ready version __xfs_attr_rmtval_remove. We will rename __xfs_attr_rmtval_remove back to xfs_attr_rmtval_remove when we are done. xfs_attr_rmtval_remove itself is still in use by the set routines (used during a rename). For reasons of preserving existing function, we modify xfs_attr_rmtval_remove to call xfs_defer_finish when the flag is set. Similar to how xfs_attr_remove_args does here. Once we transition the set routines to be delay ready, xfs_attr_rmtval_remove is no longer used and will be removed. This patch also adds a new struct xfs_delattr_context, which we will use to keep track of the current state of an attribute operation. The new xfs_delattr_state enum is used to track various operations that are in progress so that we know not to repeat them, and resume where we left off before EAGAIN was returned to cycle out the transaction. Other members take the place of local variables that need to retain their values across multiple function calls. See xfs_attr.h for a more detailed diagram of the states.

Originally we added this patch to help modularize the attr code in preparation for delayed attributes and the state machine it requires. However, later reviews found that this slightly alters the transaction handling as the helper function is ambiguous as to whether the transaction is diry or clean.

2021-05-29selftests: kvm: fix overlapping addresses in memslot_perf_testPaolo Bonzini1-1/+1
vm_create allocates memory and maps it close to GPA. This memory is separate from what is allocated in subsequent calls to vm_userspace_mem_region_add, so it is incorrect to pass the test memory size to vm_create_default. Just pass a small fixed amount of memory which can be used later for page table, otherwise GPAs are already allocated at MEM_GPA and the test aborts.
