From 03f6e92bdd467aed9d7571a571868563ae6ad288 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 28 Apr 2008 02:14:32 -0700 Subject: [PATCH] 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 --- fs/dquot.c | 10 +++++- fs/reiserfs/super.c | 2 +- include/linux/quota.h | 5 --- include/linux/quotaops.h | 71 ++++++++++++++++++++++++++++------------ 4 files changed, 60 insertions(+), 28 deletions(-) diff --git a/fs/dquot.c b/fs/dquot.c index 24eef582d2a0..fc26d1097d3c 100644 --- a/fs/dquot.c +++ b/fs/dquot.c @@ -289,7 +289,15 @@ static void wait_on_dquot(struct dquot *dquot) mutex_unlock(&dquot->dq_lock); } -#define mark_dquot_dirty(dquot) ((dquot)->dq_sb->dq_op->mark_dirty(dquot)) +static inline int dquot_dirty(struct dquot *dquot) +{ + return test_bit(DQ_MOD_B, &dquot->dq_flags); +} + +static inline int mark_dquot_dirty(struct dquot *dquot) +{ + return dquot->dq_sb->dq_op->mark_dirty(dquot); +} int dquot_mark_dquot_dirty(struct dquot *dquot) { diff --git a/fs/reiserfs/super.c b/fs/reiserfs/super.c index 393cc22c1717..3e1972d31e44 100644 --- a/fs/reiserfs/super.c +++ b/fs/reiserfs/super.c @@ -304,7 +304,7 @@ static int finish_unfinished(struct super_block *s) /* Turn quotas off */ for (i = 0; i < MAXQUOTAS; i++) { if (sb_dqopt(s)->files[i]) - vfs_quota_off_mount(s, i); + vfs_quota_off(s, i); } if (ms_active_set) /* Restore the flag back */ diff --git a/include/linux/quota.h b/include/linux/quota.h index 326cb80e3867..48556b039b1c 100644 --- a/include/linux/quota.h +++ b/include/linux/quota.h @@ -331,11 +331,6 @@ struct quota_info { struct quota_format_ops *ops[MAXQUOTAS]; /* Operations for each type */ }; -/* Inline would be better but we need to dereference super_block which is not defined yet */ -int mark_dquot_dirty(struct dquot *dquot); - -#define dquot_dirty(dquot) test_bit(DQ_MOD_B, &(dquot)->dq_flags) - #define sb_has_quota_enabled(sb, type) ((type)==USRQUOTA ? \ (sb_dqopt(sb)->flags & DQUOT_USR_ENABLED) : (sb_dqopt(sb)->flags & DQUOT_GRP_ENABLED)) diff --git a/include/linux/quotaops.h b/include/linux/quotaops.h index 5110201a4159..1aac25511f07 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.
