Revision 45b00c94be33db5d00595046663163ce55cbbfb9 authored by Linus Torvalds on 11 June 2016, 18:42:08 UTC, committed by Linus Torvalds on 11 June 2016, 18:42:08 UTC
Pull SCSI fixes from James Bottomley:
"Two current fixes:
- one affects Qemu CD ROM emulation, which stopped working after the
updates in SCSI to require VPD pages from all conformant devices.
Fix temporarily by blacklisting Qemu (we can relax later when they
come into compliance).
- The other is a fix to the optimal transfer size. We set up a
minefield for ourselves by being confused about whether the limits
are in bytes or sectors (SCSI optimal is in blocks and the queue
parameter is in bytes).
This tries to fix the problem (wrong setting for queue limits
max_sectors) and make the problem more obvious by introducing a
wrapper function"

help
If you say Y here, you will be able to set per user limits for disk
usage (also called disk quotas). Currently, it works for the
ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems.
Note that gfs2 and xfs use their own quota system.
Ext3, ext4 and reiserfs also support journaled quotas for which
you don't need to run quotacheck(8) after an unclean shutdown.
For further details, read the Quota mini-HOWTO, available from
<http://www.tldp.org/docs.html#howto>, or the documentation provided
with the quota tools. Probably the quota support is only useful for
multi user systems. If unsure, say N.

help
If you say Y here, quota warnings (about exceeding softlimit, reaching
hardlimit, etc.) will be reported through netlink interface. If unsure,
say Y.
config PRINT_QUOTA_WARNING
bool "Print quota warnings to console (OBSOLETE)"
depends on QUOTA
default y
help
If you say Y here, quota warnings (about exceeding softlimit, reaching
hardlimit, etc.) will be printed to the process' controlling terminal.
Note that this behavior is currently deprecated and may go away in
future. Please use notification via netlink socket instead.
config QUOTA_DEBUG
bool "Additional quota sanity checks"
depends on QUOTA
default n
help
If you say Y here, quota subsystem will perform some additional
sanity checks of quota internal structures. If unsure, say N.
# Generic support for tree structured quota files. Selected when needed.

tristate "Old quota format support"
depends on QUOTA
help
This quota format was (is) used by kernels earlier than 2.4.22. If
you have quota working and you don't want to convert to new quota
format say Y here.
config QFMT_V2
tristate "Quota format vfsv0 and vfsv1 support"
depends on QUOTA
select QUOTA_TREE
help
This config option enables kernel support for vfsv0 and vfsv1 quota
formats. Both these formats support 32-bit UIDs/GIDs and vfsv1 format
also supports 64-bit inode and block quota limits. If you need this
functionality say Y here.
