This makes those interfaces readily available throughout the code base. The macros that redefine DTRACE_PROBE* to use Linux tracepoints are also still provided by trace.h, so it is a prerequisite for the other trace_*.h headers. These new Linux implementation-specific headers do introduce a small divergence from upstream ZFS in several core C files, but this should not present a significant maintenance burden.

8659 static dtrace probes unavailable on non-GPL modules ZFS tracing efforts are hampered by the inability to access zfs static probes(probes using DTRACE_PROBE macros). The probes are available via tracepoints for GPL modules only. The build could be modified to generate a function for each unique DTRACE_PROBE invocation. These could be then accessed via kprobes.

Use native inode->i_nlink instead of znode->z_links A mostly mechanical change, taking into account i_nlink is 32 bits vs ZFS's 64 bit on-disk link count. We revert "xattr dir doesn't get purged during iput" (ddae16a) as this is a more Linux-integrated fix for the same issue. In addition, setting the initial link count on a new node has been changed from setting one less than required in zfs_mknode() then incrementing to the correct count in zfs_link_create() (which was somewhat bizarre in the first place), to setting the correct count in zfs_mknode() and not incrementing it in zfs_link_create(). This both means we no longer set the link count in sa_bulk_update() twice (once for the initial incorrect count then again for the correct count), as well as adhering to the Linux requirement of not incrementing a zero link count without I_LINKABLE (see linux commit f4e0c30c).

Remove dummy znode from zvol_state struct zvol_state contains a dummy znode, which is around 1KB on x64, only for zfs_range_lock. But in reality, other than z_range_lock and z_range_avl, zfs_range_lock only need znode on regular file, which means we add 1KB on a structure and gain nothing. In this patch, we remove the dummy znode for zvol_state. In order to do that, we also need to refactor zfs_range_lock a bit. We move z_range_lock and z_range_avl pair out of znode_t to form zfs_rlock_t. This new struct replaces znode_t as the main handle inside the range lock functions. We also add pointers to z_size, z_blksz, and z_max_blksz so range lock code doesn't depend on znode_t. This allows non-ZPL consumers like Lustre to use the range locks with their equivalent znode_t structure.

Remove znode's z_uid/z_gid member Remove duplicate z_uid/z_gid member which are also held in the generic vfs inode struct. This is done by first removing the members from struct znode and then using the KUID_TO_SUID/KGID_TO_SGID macros to access the respective member from struct inode. In cases where the uid/gids are being marshalled from/to disk, use the newly introduced zfs_(uid|gid)_(read|write) functions to properly save the uids rather than the internal kernel representation.

Linux 4.16 compat: inode_set_iversion() A new interface was added to manipulate the version field of an inode. Add a inode_set_iversion() wrapper for older kernels and use the new interface when available. The i_version field was dropped from the trace point due to the switch to an atomic64_t i_version type.

Remove duplicate typedefs from trace.h Older versions of GCC (e.g. GCC 4.4.7 on RHEL6) do not allow duplicate typedef declarations with the same type. The trace.h header contains some typedefs to avoid 'unknown type' errors for C files that haven't declared the type in question. But this causes build failures for C files that have already declared the type. Newer versions of GCC (e.g. v4.6) allow duplicate typedefs with the same type unless pedantic error checking is in force. To support the older versions we need to remove the duplicate typedefs. Removal of the typedefs means we can't built tracepoints code using those types unless the required headers have been included. To facilitate this, all tracepoint event declarations have been moved out of trace.h into separate headers. Each new header is explicitly included from the C file that uses the events defined therein. The trace.h header is still indirectly included form zfs_context.h and provides the implementation of the dprintf(), dbgmsg(), and SET_ERROR() interfaces. This makes those interfaces readily available throughout the code base. The macros that redefine DTRACE_PROBE* to use Linux tracepoints are also still provided by trace.h, so it is a prerequisite for the other trace_*.h headers. These new Linux implementation-specific headers do introduce a small divergence from upstream ZFS in several core C files, but this should not present a significant maintenance burden.

8659 static dtrace probes unavailable on non-GPL modules ZFS tracing efforts are hampered by the inability to access zfs static probes(probes using DTRACE_PROBE macros). The probes are available via tracepoints for GPL modules only. The build could be modified to generate a function for each unique DTRACE_PROBE invocation. These could be then accessed via kprobes.
