The kernel I'm using is gentoo-sources-2.6.24-r4 My top-most build errors when compiling sys-fs/cloop-2.05 are: make[1]: Entering directory `/usr/src/linux-2.6.24-gentoo-r4' CC [M] /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.o /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c:119: warning: 'request_queue_t' is deprecated /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c:265: warning: 'request_queue_t' is deprecated /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c: In function 'make_clo_request': /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c:353: error: too many arguments to function 'bio_endio' /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c: In function 'clo_set_file': /var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.c:390: warning: 'request_queue_t' is deprecated make[2]: *** [/var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829/compressed_loop.o] Error 1 make[1]: *** [_module_/var/tmp/portage/sys-fs/cloop-2.05/work/cloop-2.05~20060829] Error 2 There are newer versions of cloop available, which should be used for this kernel version. I've tried one out already; it builds, installs, and loads, but I haven't tested it yet. I posted notes about making an ebuild for this in the following forum post: http://forums.gentoo.org/viewtopic-t-690130.html

It seems that I'd overlooked the more recent ebuild, cloop-2.624.ebuild, which *is* compatible with 2.6.24-r4.
