From 03f6e92bdd467aed9d7571a571868563ae6ad288 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 28 Apr 2008 02:14:32 -0700 Subject: quota: various style cleanups Cleanups in quota code: Change __inline__ to inline. Change some macros to inline functions. Remove vfs_quota_off_mount() macro. DQUOT_OFF() should be (0) is CONFIG_QUOTA is disabled. Move declaration of mark_dquot_dirty and dirty_dquot from quota.h to dquot.c [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Jan Kara Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/quotaops.h | 71 ++++++++++++++++++++++++++++++++++-------------- 1 file changed, 50 insertions(+), 21 deletions(-) (limited to 'include/linux/quotaops.h') diff --git a/include/linux/quotaops.h b/include/linux/quotaops.h index 5110201a415..1aac25511f0 100644 --- a/include/linux/quotaops.h +++ b/include/linux/quotaops.h @@ -41,7 +41,6 @@ extern int vfs_quota_on(struct super_block *sb, int type, int format_id, char *p extern int vfs_quota_on_mount(struct super_block *sb, char *qf_name, int format_id, int type); extern int vfs_quota_off(struct super_block *sb, int type); -#define vfs_quota_off_mount(sb, type) vfs_quota_off(sb, type) extern int vfs_quota_sync(struct super_block *sb, int type); extern int vfs_get_dqinfo(struct super_block *sb, int type, struct if_dqinfo *ii); extern int vfs_set_dqinfo(struct super_block *sb, int type, struct if_dqinfo *ii); @@ -59,7 +58,7 @@ extern struct quotactl_ops vfs_quotactl_ops; /* It is better to call this function outside of any transaction as it might * need a lot of space in journal for dquot structure allocation. */ -static __inline__ void DQUOT_INIT(struct inode *inode) +static inline void DQUOT_INIT(struct inode *inode) { BUG_ON(!inode->i_sb); if (sb_any_quota_enabled(inode->i_sb) && !IS_NOQUOTA(inode)) @@ -67,7 +66,7 @@ static __inline__ void DQUOT_INIT(struct inode *inode) } /* The same as with DQUOT_INIT */ -static __inline__ void DQUOT_DROP(struct inode *inode) +static inline void DQUOT_DROP(struct inode *inode) { /* Here we can get arbitrary inode from clear_inode() so we have * to be careful.
