Revision 1.8, Wed Sep 12 17:09:56 2007 UTC (10 years, 1 month ago) by tes.longdrop.melbourne.sgi.com
Update 2.6.x-xfs to 2.6.23-rc4. Also update fs/xfs with external mainline changes. There were 12 such missing commits that I detected: -------- commit ad690ef9e690f6c31f7d310b09ef1314bcec9033 Author: Al Viro <viro@ftp.linux.org.uk> xfs ioctl __user annotations commit 20c2df83d25c6a95affe6157a4c9cac4cf5ffaac Author: Paul Mundt <lethal@linux-sh.org> mm: Remove slab destructors from kmem_cache_create(). commit d0217ac04ca6591841e5665f518e38064f4e65bd Author: Nick Piggin <npiggin@suse.de> mm: fault feedback #1 commit 54cb8821de07f2ffcd28c380ce9b93d5784b40d7 Author: Nick Piggin <npiggin@suse.de> mm: merge populate and nopage into fault (fixes nonlinear) commit d00806b183152af6d24f46f0c33f14162ca1262a Author: Nick Piggin <npiggin@suse.de> mm: fix fault vs invalidate race for linear mappings commit a569425512253992cc64ebf8b6d00a62f986db3e Author: Christoph Hellwig <hch@infradead.org> knfsd: exportfs: add exportfs.h header commit 831441862956fffa17b9801db37e6ea1650b0f69 Author: Rafael J.
