2017-08-14uapi/linux/quota.h: Do not include linux/errno.hFlorian Weimer1-1/+0
linux/errno.h is very sensitive to coordination with libc headers. Nothing in linux/quota.h needs it, so this change allows using this header in more contexts. Signed-off-by: Florian Weimer <[email protected]> Signed-off-by: Jan Kara <[email protected]>

2016-02-08quota: add new quotactl Q_GETNEXTQUOTAEric Sandeen1-0/+14
Q_GETNEXTQUOTA is exactly like Q_GETQUOTA, except that it will return quota information for the id equal to or greater than the id requested. In other words, if the requested id has no quota, the command will return quota information for the next higher id which does have a quota set. If no higher id has an active quota, -ESRCH is returned. This allows filesystems to do efficient iteration in kernelspace, much like extN filesystems do in userspace when asked to report all active quotas. This does require a new data structure for userspace, as the current structure does not include an ID for the returned quota information. Today, Ext4 with a hidden quota inode requires getpwent-style iterations, and for systems which have i.e. LDAP backends, this can be very slow, or even impossible if iteration is not allowed in the configuration.

2015-01-21quota: Cleanup flags definitionsJan Kara1-1/+13
Currently all quota flags were defined just in kernel-private headers. Export flags readable / writeable from userspace to userspace via include/uapi/linux/quota.h. Signed-off-by: Jan Kara <[email protected]>
