This function only had one caller left, and that caller only called it for leaf blocks, hence one branch of the "if" was never taken. In addition the call to get_left had already verified the metadata type, so the function can be reduced to a single line of code in its caller. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Currently gfs2 issues barrier unconditionally. There are various reasons to disable them, be that just for testing or for stupid devices flushing large battert backed caches. Add a nobarrier option that matches xfs and btrfs for this. Also add a symmetric barrier option to turn it back on at remount time.

GFS2 now has three new mount options, statfs_quantum, quota_quantum and statfs_percent. statfs_quantum and quota_quantum simply allow you to set the tunables of the same name. Setting setting statfs_quantum to 0 will also turn on the statfs_slow tunable. statfs_percent accepts an integer between 0 and 100. Numbers between 1 and 100 will cause GFS2 to do any early sync when the local number of blocks free changes by at least statfs_percent from the totoal number of blocks free. Setting statfs_percent to 0 disables this. Signed-off-by: NBenjamin Marzinski <bmarzins@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This adds support to GFS2 to send quota warnings via netlink. Also it removes a stray \r which was left over from when the code used to print warnings on the console. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

由 Steven Whitehouse 提交于
Sending a message to userspace in a generic format to warn of events (e.g. quota exceeded) in the quota subsystem is a generically useful feature. This patch makes some minor changes to the send_message function from dquot.c renaming it quota_send_message, moving it to quota.c and exporting it for use by filesystems which do not use the dquot code.

This adds support for viewing the current GFS2 quota settings via the XFS quota API. The setting of quotas will be addressed in a later patch.

Both of these functions contained confusing and in one case duplicate code. This patch adds a new check in do_glock() so that we report -ENOENT if we are asked to sync a quota entry which doesn't exist. Due to the previous patch this is now reported correctly to userspace. Also there are a few new comments, and I hope that the code is easier to understand now. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The plan is to add further operations to the gfs2_quotactl_ops in future patches. The sync operation is easy, so we start with that one. We plan to use the XFS quota control functions because they more closely match the GFS2 ones. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

These two functions are altered so that gfs2_quota_sync may in future be called directly from the VFS. The GFS2 superblock changes to a VFS super block and there is an addition of an int argument which is currently ignored. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

GFS2 needs to call this from under a glock, so we need GFP_NOFS and I suspect that other filesystems might require this too. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The other patches in this series have been building towards being able to support cached ACLs like other filesystems. The only real difference with GFS2 is that we have to invalidate the cache when we drop a glock, but that is dealt with in earlier patches. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

To prepare for support for caching of ACLs, this cleans up the GFS2 ACL support by pushing the xattr code back into xattr.c and changing the acl_get function into one which only returns ACLs so that we can drop the caching function into it shortly.

This code has been shamelessly stolen from XFS at the suggestion of Christoph Hellwig. I've not added support for cached ACLs so far... watch for that in a later patch, although this is designed in such a way that they should be easy to add.

We have a long term plan to use the "-o meta" flag to GFS2 mounts to access the alternate root which is used to store metadata for a GFS2 filesystem. This will allow us to eventually remove support for the gfs2meta filesystem type (which is in any case just a "front end" to the gfs2 filesystem type with the meta/master root). Currently the "-o meta" option is only taken into account on the initial mount of the filesystem. Subsequent mounts of the same filesystem (i.e. on the same device) result in basically the same as bind mounting the root of the original mount. This patch changes that by using what is more or less a copy of get_sb_bdev() and extending it so that it will take into account the alternate root in all cases. The main difference is that we have to parse the mount options a bit earlier. We can then use them to select the appropriate root towards the end of the function. In addition this also fixes a bug where it was possible (but certainly not desirable) to set different ro/rw options for the meta root when mounted via the gfs2meta fs compared with the original mount.

request_region should be used with release_region, not request_mem_region. Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c, the problem is actually the other way around; request_mem_region should be used instead of request_region.

On the parisc architecture we face for each and every loaded kernel module this kernel "badness warning": sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text' Badness at fs/sysfs/dir.c:487 Reason for that is, that on parisc all kernel modules do have multiple .text sections due to the usage of the -ffunction-sections compiler flag which is needed to reach all jump targets on this platform. An objdump on such a kernel module gives: Sections: Idx Name Size VMA LMA File off Algn 0 .note.gnu.build-id 00000024 00000000 00000000 00000034 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .text 00000000 00000000 00000000 00000058 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .text.ac97_bus_match 0000001c 00000000 00000000 00000058 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 3 .text 00000000 00000000 00000000 000000d4 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE ... Since the .text sections are empty (size of 0 bytes) and won't be loaded by the kernel module loader anyway, I don't see a reason why such sections need to be listed under /sys/module/<module_name>/sections/<section_name> either. The attached patch does solve this issue by not exporting section names which are empty.
