in contrast to gpfs_getacl_alloc which always puts the
ACL on talloc_tos(), this one allows to specify the memory
context and if the caller is interested in the raw ACL blob
or a structured version

sys_acl_init returns a SMB_ACL_T with zero entries in the acl array

This makes it clear which context the returned SD is allocated on, as
a number of callers do not want it on talloc_tos().
As the ACL transformation allocates and then no longer needs a great
deal of memory, a talloc_stackframe() call is used to contain the
memory that is not returned further up the stack.
Andrew Bartlett
This changes from allocation on NULL to allocation on the supplied
memory context.
Currently that supplied context is talloc_tos() at the the final consumer of
the ACL.

The query of the fileset quota needs to determine the file set id first.
With the currently available interface, this requires opening the file
to get a file descriptor. For files, this open can fail when a share
mode is set.
Workaround this by querying the fileset id on the directory instead.
The proper solution would be getting an interface for getting the
fileset id that does not require opening the file.

It was separated out because formerly our async I/O was not properly

The acl element is changed to be a talloc child, and is no longer one element
longer than requested by virtue of the acl[1] base pointer.
This also avoids one of the few remaining cases of over-allocation of a structure.

gpfs_quotactl can return a non-zero softquota gracetime even when no
softquota has been set. This could lead to "disk full" being reported to
a client. The easiest fix is to check for a valid softquota before
checking the softquota gracetime.
gpfs2smb_acl can leave errno!=0 around even if it returned a correct
result!=NULL. We can only rely on errno being set if another error
condition (in this case result==NULL) indicates an error. If
result!=NULL, errno is undefined and can be anything. This leads to
SAFE_FREE(result) further down even in the success case.

With "gpfs:acl=no" you can pass the acl calls to the next SMB_VFS module.

Don't use the mode for the get_acl call that surpresses
inherited deny ACE's. This is now possible since
the inherited ACE flag exists now in GPFS and Samba.
Now that we always require a 64 bit off_t, we no longer need SMB_OFF_T.

if setting the lease in GPFS failed, there is not much sense in trying
to set a lease just locally that would not inform us of openers
on other cluster nodes
GPFS provides the gpfs_prealloc call. Implement the fallocate
callback with mode VFS_FALLOCATE_EXTEND_SIZE using this call.
There is no support for VFS_FALLOCATE_KEEP_SIZE, so report
this mode as not available.
When a client requests the information about free space and space used,
adjust the reported values according to quotas in the GPFS file system:
- Retrieve quotas for the current user, current group and fileset for
the top level of the share.
- If the soft block quota grace time has expired, report disk as full.
- If a hard block quota has been exceeded, report disk as full.
- If none of the hard block quotas been exceeded, report
share size and free space according to the lowest limits found in
the quotas.
- If no applicable hard block quota has been set, report the
information from the statfs call.
This feature is disabled by default and has to be enabled by setting the
option gpfs:dfreequota.
Setting the creation time through SetFileTime on a GPFS file system and
querying it with GetFileTime shows a mismatch.
The vfs_gpfs module first retrieves the information from the operating
system and the flag st_ex_calculated_birthtime is set to false. When
vfs_gpfs retrieves the birthtime from GPFS the flag
st_ex_calculated_birthtime has to be set to true. Otherwise the birth
time will get overwritten by a call to update_stat_ex_mtime, reporting
the wrong time to a client system.
