From 3d544f411f2971eb82f5c52322251eb04494542a Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Tue, 24 Mar 2009 11:59:23 +0200 Subject: kmemtrace, fs, security: move alloc_secdata() and free_secdata() to linux/security.h Impact: cleanup We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace changes), but this is not possible currently without breaking the build because fs.h has implicit include file depedencies: it uses GFP_* types in inlines but does not include gfp.h. In practice most fs.h using .c files get gfp.h included implicitly, via an indirect route: via rcupdate.h inclusion - so this underlying problem gets masked in practice. So we want to solve fs.h's dependency on gfp.h. gfp.h can not be included here directly because it is not exported and it would break the build the following way: /home/mingo/tip/usr/include/linux/bsg.h:11: found __[us]{8,16,32,64} type without #include /home/mingo/tip/usr/include/linux/fs.h:11: included file 'linux/gfp.h' is not exported make[3]: *** [/home/mingo/tip/usr/include/linux/.check] Error 1 make[2]: *** [linux] Error 2 As suggested by Alexey Dobriyan, move alloc_secdata() and free_secdata() to linux/security.h - they belong there. This also cleans fs.h of GFP_* usage.

This problem gets masked in practice because most fs.h using sites use rcupreempt.h (and other headers) which includes percpu.h which brings in asm/page.h indirectly. We cannot add asm/page.h to asm/fs.h because page.h is not an exported header. Move simple_transaction_set() to the other simple-transaction file helpers in fs/libfs.c. This removes the include file hell and also reduces kernel size a bit.
