Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
Touches IRQ or DMA behavior; this matters for the representative real-device path.
Allocates kernel memory; connect allocation flags and lifetime to context constraints.
Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotated Snippet

Known issues :
	* Please read the associated RELEASE-NOTES file !!!
	* This source release intended for upstream kernel releases only!

Changes from 20050323 to 20050413

	* Changed version number to 8.0.28
	* Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now
	  requires a function which takes an unsigned int for gfp_flags.
	* Removed pci dma sync calls to coherent/consistent pci memory.
	* Merged patch from Christoph Hellwig <hch@lst.de>: split helpers
	  for fabric and nport logins out of lpfc_cmpl_els_flogi.
	* Removed sysfs attributes that are used to dump the various
	  discovery lists.
	* Fix for issue where not all luns are seen.  Search all lists
	  other than unmap list in lpfc_find_target().  Otherwise INQUIRY
	  to luns on nodes in NPR or other relevant states (PLOGI,
	  PRLI...) are errored back and scan() terminates.
	* Removed FC_TRANSPORT_PATCHESxxx defines.  They're in 2.6.12-rc1.
	* Compare return value of lpfc_scsi_tgt_reset against SCSI
	  midlayer codes SUCCESS/FAILED which that function returns rather
	  than SLI return code.
	* Removed extraneous calls to lpfc_sli_next_iotag which should
	  only be called from lpfc_sli_submit_iocb.  Also make
	  lpfc_sli_next_iotag static.
	* Added PCI ID for LP10000-S.
	* Changes in lpfc_abort_handler(): Return SUCCESS if we did not
	  find command in both TX and TX completion queues.  Return ERROR
	  if we timed out waiting for command to complete after abort was
	  issued.
	* Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent
	  interpretation of stale sense length when the command completes
	  - was causing spurious 0710 messages.
	* Moved clearing of host_scribble inside host_lock in IO
	  completion path.
	* Fixed a bunch of mixed tab/space indentation.
	* Allow hex format numbers in sysfs attribute setting.  Fix
	  application hang when invalid numbers are used in sysfs
	  settings.
	* Removed extra iotag allocation by lpfc_abort_handler.
	* Clear host_scribble in the scsi_cmnd structure when failing in
	  queuecommand.
	* Changed logic at top of lpfc_abort_handler so that if the
	  command's host_scibble field is NULL, return SUCCESS because the
	  driver has already returned the command to the midlayer.

Changes from 20050308 to 20050323

	* Changed version number to 8.0.27
	* Changed a few lines from patch submitted by Christoph Hellwig
	  (3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an
	  equivalent MAILBOX_CMDSIZE macro.
	* Merged patch from Christoph Hellwig (3/19): some misc patches
	  against the latest drivers:
	  - stop using volatile.  if you need special ordering use memory
	    barriers but that doesn't seem to be the case here
	  - switch lpfc_sli_pcimem_bcopy to take void * arguments.
	  - remove typecast for constants - a U postfix marks them
	    unsigned int in C
	  - add a MAILBOX_CMD_SIZE macro, as most users of
	    MAILBOX_CMD_WSIZE didn't really want the word count
	  - kill struct lpfc_scsi_dma_buf and embedded the two members
	    directly in struct lpfc_scsi_buf
	  - don't call dma_sync function on allocations from
	    pci_pool_alloc - it's only for streaming mappings (pci_map_*)
	* Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't
	  ever used by the driver, just reported to userspace (and that in
	  a multi-value file which is against the sysfs guidelines).
	* Change pci_module_init to pci_register_module() with appropriate
	  ifdefs.

Annotation

Detected declarations: `function schedule_timeout`.
Atlas domain: Support Tooling And Documentation / Documentation.
Implementation status: integration implementation candidate.
Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
