Name:Convert allocated space back to in-memory reserved quotas
Proto:void dquot_reclaim_space_nodirty(struct inode *inode, qsize_t number)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct inode * | inode | |
qsize_t | number |
1811 | If Not dquot_active(inode) Then |
1812 | spin_lock( & _blocks, i_bytes, maybe i_size ) |
1813 | de_reserved_space is managed internally by quota, and protected by* i_lock similar to i_blocks+i_bytes. += number |
1814 | __inode_sub_bytes(inode, number) |
1815 | spin_unlock( & _blocks, i_bytes, maybe i_size ) |
1816 | Return |
1821 | spin_lock( & _blocks, i_bytes, maybe i_size ) |
1827 | spin_lock( & Lock protecting dq_dqb changes ) |
1828 | If WARN_ON_ONCE(current used space < number) Then number = current used space |
1831 | current used space -= number |
1832 | spin_unlock( & Lock protecting dq_dqb changes ) |
1836 | de_reserved_space is managed internally by quota, and protected by* i_lock similar to i_blocks+i_bytes. += number |
