This patch pulls xfs_attr_rmtval_invalidate out of xfs_attr_rmtval_remove and into the calling functions. Eventually __xfs_attr_rmtval_remove will replace xfs_attr_rmtval_remove when we introduce delayed attributes. These functions are exepcted to return -EAGAIN when they need a new transaction. Because the invalidate does not need a new transaction, we need to separate it from the rest of the function that does. This will enable __xfs_attr_rmtval_remove to smoothly replace xfs_attr_rmtval_remove later. Signed-off-by:

Refactor xfs_attr_rmtval_remove to add helper function __xfs_attr_rmtval_remove. We will use this later when we introduce delayed attributes. This function will eventually replace xfs_attr_rmtval_remove Signed-off-by:

New delayed allocation routines cannot be handling transactions so pull them out into the calling functions Signed-off-by:

Because new delayed attribute routines cannot roll transactions, we carve off the parts of xfs_attr_rmtval_remove that we can use. This will help to reduce repetitive code later when we introduce delayed attributes. Signed-off-by:

To help pre-simplify xfs_attr_set_args, we need to hoist transaction handling up, while modularizing the adjacent code down into helpers. In this patch, hoist the commit in xfs_attr_try_sf_addname up into the calling function, and also pull the attr list creation down. Signed-off-by:

Split out new helper function xfs_attr_leaf_try_add from xfs_attr_leaf_addname. Because new delayed attribute routines cannot roll transactions, we split off the parts of xfs_attr_leaf_addname that we can use, and move the commit into the calling function. Signed-off-by:

Break xfs_attr_rmtval_set into two helper functions xfs_attr_rmt_find_hole and xfs_attr_rmtval_set_value. xfs_attr_rmtval_set rolls the transaction between the helpers, but delayed operations cannot. We will use the helpers later when constructing new delayed attribute routines. Signed-off-by:

Delayed operations cannot return error codes. So we must check for these conditions first before starting set or remove operations Signed-off-by:

This patch adds a new functions to check for the existence of an attribute. Subroutines are also added to handle the cases of leaf blocks, nodes or shortform. Common code that appears in existing attr add and remove functions have been factored out to help reduce the appearance of duplicated code. We will need these routines later for delayed attributes since delayed operations cannot return error codes. Signed-off-by:

Every call to xfs_da_state_alloc() also requires setting up state->args and state->mp Change xfs_da_state_alloc() to receive an xfs_da_args_t as argument and return a xfs_da_state_t with both args and mp already set. Signed-off-by:

xlog_ticket_alloc() is always called under NOFS context, except from unmount path, which eitherway is holding many FS locks, so, there is no need for its callers to keep passing allocation flags into it. change xlog_ticket_alloc() to use default kmem_cache_zalloc(), remove its alloc_flags argument, and always use GFP_NOFS | __GFP_NOFAIL flags.

Use kmem_cache_alloc() directly. All kmem_zone_alloc() users pass 0 as flags, which are translated into: GFP_KERNEL | __GFP_NOWARN, and kmem_zone_alloc() loops forever until the allocation succeeds. We can use __GFP_NOFAIL to tell the allocator to loop forever rather than doing it ourself, and because the allocation will never fail, we do not need to use __GFP_NOWARN anymore. Hence, all callers can be converted to use GFP_KERNEL | __GFP_NOFAIL Signed-off-by:

The ondisk dquot stores the quota record type in the flags field. Rename this field to d_type to make the _type relationship between the ondisk and incore dquot more obvious. Signed-off-by:

Create an XFS_DQTYPE_ANY mask for ondisk dquots flags, and use that to ensure that we never accept any garbage flags when we're loading dquots. While we're at it, restructure the quota type flag checking to use the proper masking. Note that I plan to add y2038 support soon, which will require a new xfs_dqtype_t flag for extended timestamp support, hence all the work to make the type masking work correctly. Signed-off-by:

Create a new type (xfs_dqtype_t) to represent the type of an incore dquot (user, group, project, or none). Rename the incore dquot's dq_flags field to q_type. This allows us to replace all the "uint type" arguments to the quota functions with "xfs_dqtype_t type", to make it obvious when we're passing a quota type argument into a function. Signed-off-by:

When XFS' quota functions take a parameter for the quota type, they only care about the three quota record types (user, group, project). Internal state flags and whatnot should never be passed by callers and are an error. Now that we've moved responsibility for filtering out internal state to the callers, we can drop the masking everywhere else. In other words, if you call a quota function, you must only pass in one of XFS_DQTYPE_{USER,GROUP,PROJ}. Signed-off-by: -

xfs_qm_reset_dqcounts (aka quotacheck) is the only xfs_dqblk_verify caller that actually knows the specific quota type that it's looking for. Since everything else just pass in type==0 (including the buffer verifier), drop the parameter and open-code the check like xfs_dquot_from_disk already does. Signed-off-by:

Add all the xfs_dquot fields to the tracepoint for that type; add a new tracepoint type for the qtrx structure (dquot transaction deltas); and use our new tracepoints. This makes it easier for the author to trace changes to dquot counters for debugging. Signed-off-by:

Currently, xfs quotas have the ability to send netlink warnings when a user exceeds the limits. They also have all the support code necessary to convert softlimit warnings into failures if the number of warnings exceeds a limit set by the administrator. Unfortunately, we never actually increase the warning counter, so this never actually happens. Make it so we actually do something useful with the warning counts. Signed-off-by:
