From 12b4629a9fb80fecaebadc217b13b8776ed8dbef Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 24 Dec 2013 21:19:23 +0200 Subject: libceph: all features fields must be u64 In preparation for ceph_features.h update, change all features fields from unsigned int/u32 to u64. (ceph.git has ~40 feature bits at this point.)

This changes the existing behaviour: - for buffers (ceph_buffer_new()), from trying to kmalloc() everything and using vmalloc() just as a fallback - for messages (ceph_msg_new()), from going to vmalloc() for anything bigger than a page - for messages (ceph_msg_new()), from disallowing vmalloc() to use high memory Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil --- include/linux/ceph/libceph.h | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) (limited to 'include/linux/ceph/libceph.h') diff --git a/include/linux/ceph/libceph.h b/include/linux/ceph/libceph.h index 7d704db60cbb..2f49aa4c4f7f 100644 --- a/include/linux/ceph/libceph.h +++ b/include/linux/ceph/libceph.h @@ -173,15 +173,18 @@ static inline int calc_pages_for(u64 off, u64 len) (off >> PAGE_CACHE_SHIFT); } +extern struct kmem_cache *ceph_inode_cachep; +extern struct kmem_cache *ceph_cap_cachep; +extern struct kmem_cache *ceph_dentry_cachep; +extern struct kmem_cache *ceph_file_cachep; + /* ceph_common.c */ extern bool libceph_compatible(void *data); extern const char *ceph_msg_type_name(int type); extern int ceph_check_fsid(struct ceph_client *client, struct ceph_fsid *fsid); -extern struct kmem_cache *ceph_inode_cachep; -extern struct kmem_cache *ceph_cap_cachep; -extern struct kmem_cache *ceph_dentry_cachep; -extern struct kmem_cache *ceph_file_cachep; +extern void *ceph_kvmalloc(size_t size, gfp_t flags); +extern void ceph_kvfree(const void *ptr); extern struct ceph_options *ceph_parse_options(char *options, const char *dev_name, const char *dev_name_end, -- cgit v1.2.3
