xfs: refactor log recovery item sorting into a generic dispatch structure

2020-05-08T15:49:58+00:00

Create a generic dispatch structure to delegate recovery of different log item types into various code modules. This will enable us to move code specific to a particular log item type out of xfs_log_recover.c and into the log item source. The first operation we virtualize is the log item sorting.

xfs: stop CONFIG_XFS_DEBUG from changing compiler flags

2020-05-04T16:03:15+00:00

I ran into a linker warning in XFS that originates from a mismatch between libelf, binutils and objtool when certain files in the kernel are built with "gcc -g": x86_64-linux-ld: fs/xfs/xfs_trace.o: unable to initialize decompress status for section .debug_info After some discussion, nobody could identify why xfs sets this flag here. CONFIG_XFS_DEBUG used to enable lots of unrelated settings, but now its main purpose is to enable extra consistency checks and assertions that are unrelated to the debug info. Remove the Makefile logic to set the flag here. If anyone relies on the debug info, this can simply be enabled again with the global CONFIG_DEBUG_INFO option. Dave Chinner writes: I'm pretty sure it was needed for the original kgdb integration back in the early 2000s. That was when SGI used to patch their XFS dev tree with kgdb and debug symbols were needed by the custom kgdb modules that were ported across from the Irix kernel debugger. ISTR that the early kcrash kernel dump analysis tools (again, originated from the Irix "icrash" kernel dump tools) had custom XFS debug scripts that needed also the debug info to work correctly... Which is a long way of saying "we don't need it anymore" instead of "nobody knows why it was set"... :) Suggested-by: Christoph Hellwig Link: https://lore.kernel.org/lkml/20200409074130.GD21033@infradead.org/ Signed-off-by: Arnd Bergmann Reviewed-by: Brian Foster Reviewed-by: Allison Collins Reviewed-by: Dave Chinner Reviewed-by: Darrick J.

xfs: introduce fake roots for ag-rooted btrees

2020-03-18T15:12:23+00:00

Create an in-core fake root for AG-rooted btree types so that callers can generate a whole new btree using the upcoming btree bulk load function without making the new tree accessible from the rest of the filesystem. It is up to the individual btree type to provide a function to create a staged cursor (presumably with the appropriate callouts to update the fakeroot) and then commit the staged root back into the filesystem.
