litmus-rt.git/fs/ubifs/Kconfig, branch 2012.2 The LITMUS^RT kernel. UBIFS: do not select KALLSYMS_ALL 2011-04-05T07:45:45+00:00 Artem Bityutskiy Artem.Bityutskiy@nokia.com 2011-03-30T08:18:54+00:00 81354de3d8691c2dedcc686cd2c167819ff0df10 All UBIFS needs is to make sure we stacktraces when UBIFS debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. Moreover, Randy Dunlap reported that UBIFS causes the following Kconfig dependency warning: warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS) The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and KALLSYMS first. This seems to be too much to select. The easiest way to go is to forget about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is enabled - that should be enough for stackdumps.

All UBIFS needs is to make sure we stacktraces when UBIFS debugging
is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL
is not necessary. Moreover, Randy Dunlap reported that UBIFS causes
the following Kconfig dependency warning:

warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL
which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS)

The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so
ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and
KALLSYMS first.

This seems to be too much to select. The easiest way to go is to forget
about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is
enabled - that should be enough for stackdumps.

Revert "lib: build list_sort() only if needed" 2010-03-07T17:54:44+00:00 Linus Torvalds torvalds@linux-foundation.org 2010-03-07T17:54:44+00:00 b8fa05719ba4349be80ce929237249b57886a203 This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504. It turns ou that not only was it missing a case (XFS) that needed it, but perhaps more importantly, people sometimes want to enable new modules that they hadn't had enabled before, and if such a module uses list_sort(), it can't easily be inserted any more. So rather than add a "select LIST_SORT" to the XFS case, just leave it compiled in. It's not all _that_ big, after all, and the inconvenience isn't worth it.

This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.
