ext4: fix quota charging for shared xattr blocks

2017-05-24T22:24:07Z

ext4_xattr_block_set() calls dquot_alloc_block() to charge for an xattr block when new references are made. However if dquot_initialize() hasn't been called on an inode, request for charging is effectively ignored because ext4_inode_info->i_dquot is not initialized yet. Add dquot_initialize() to call paths that lead to ext4_xattr_block_set(). Signed-off-by: Tahsin Erdogan Signed-off-by: Theodore Ts'o Reviewed-by: Jan Kara

quota: Add support for ->get_nextdqblk() for VFS quota

2016-02-09T12:05:23Z

Add infrastructure for supporting get_nextdqblk() callback for VFS quotas. Translate the operation into a callback to appropriate filesystem and consequently to quota format callback. Signed-off-by: Jan Kara

quota: Propagate error from ->acquire_dquot()

2015-07-23T18:59:10Z

Currently when some error happened in ->acquire_dquot(), dqget() just returned NULL. That was indistinguishable from a case when e.g. someone run quotaoff and so was generally silently ignored. However ->acquire_dquot() can fail because of ENOSPC or EIO in which case user should better know. So propagate error up from ->acquire_dquot properly. Signed-off-by: Jan Kara

quota: reorder flags in quota state

2015-03-04T15:42:46Z

Flags in struct quota_state keep flags for each quota type and some common flags. This patch reorders typed flags: Before: 0 USRQUOTA DQUOT_USAGE_ENABLED 1 USRQUOTA DQUOT_LIMITS_ENABLED 2 USRQUOTA DQUOT_SUSPENDED 3 GRPQUOTA DQUOT_USAGE_ENABLED 4 GRPQUOTA DQUOT_LIMITS_ENABLED 5 GRPQUOTA DQUOT_SUSPENDED 6 DQUOT_QUOTA_SYS_FILE 7 DQUOT_NEGATIVE_USAGE After: 0 USRQUOTA DQUOT_USAGE_ENABLED 1 GRPQUOTA DQUOT_USAGE_ENABLED 2 USRQUOTA DQUOT_LIMITS_ENABLED 3 GRPQUOTA DQUOT_LIMITS_ENABLED 4 USRQUOTA DQUOT_SUSPENDED 5 GRPQUOTA DQUOT_SUSPENDED 6 DQUOT_QUOTA_SYS_FILE 7 DQUOT_NEGATIVE_USAGE Now we can get bitmap of all enabled/suspended quota types without loop. For example suspended: (flags / DQUOT_SUSPENDED) & ((1 << MAXQUOTAS) - 1). add/remove: 0/1 grow/shrink: 3/11 up/down: 56/-215 (-159) function old new delta __dquot_initialize 423 447 +24 dquot_transfer 181 197 +16 dquot_alloc_inode 286 302 +16 dquot_reclaim_space_nodirty 316 313 -3 dquot_claim_space_nodirty 314 311 -3 dquot_resume 286 281 -5 dquot_free_inode 332 324 -8 __dquot_alloc_space 500 492 -8 dquot_disable 1944 1929 -15 dquot_quota_enable 252 236 -16 __dquot_free_space 750 734 -16 dquot_writeback_dquots 625 608 -17 __dquot_transfer 1186 1154 -32 dquot_quota_sync 299 261 -38 dquot_active.isra 54 - -54 Signed-off-by: Konstantin Khlebnikov Signed-off-by: Jan Kara

quota: Make ->set_info use structure with neccesary info to VFS and XFS

quota: Make VFS quotas use new interface for getting quota info

2015-03-04T15:06:34Z

Create new internal interface for getting information about quota which contains everything needed for both VFS quotas and XFS quotas. Make VFS use this and hook it up to Q_GETINFO. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara

quota: Add ->quota_{enable,disable} callbacks for VFS quotas

2015-01-30T11:50:32Z

Add functions which translate ->quota_enable / ->quota_disable calls into appropriate changes in VFS quota. This will enable filesystems supporting VFS quota files in system inodes to be controlled via Q_XQUOTA[ON|OFF] quotactls for better userspace compatibility. Also provide a vector for quotactl using these functions which can be used by filesystems with quota files stored in hidden system files. Signed-off-by: Jan Kara
