similar to: [PATCH] Btrfs: ratelimit the generation printk for the free space cache

Currently there are 3 different capitalisations of btrfs: used in printk()''s, BTRFS: (3 occurences), Btrfs: (1 occurence) and btrfs: (77 occurences). It''s best to have them all the same for consistency, so we canonicalise the two minority cases to btrfs:.

Hello, I want to throw this out here now that I''ve got most of the heavy lifting done for this code to make sure what I''m doing is ok for now. I''ve added an ORPHAN_DIR item key to have a hidden dir per root. Right now it just does it for whatever the default root is on mount, but I''m going to fix that to do the orphan dir check/creation on lookup of a

Hi, since the printk_ratelimit() function shouldn't be used anymore, I replaced it in a few files with printk_ratelimited(). If you wish some more patches I can send more in.

We''ve been hitting BUG()''s in btrfs_cont_expand and btrfs_fallocate and anywhere else that calls btrfs_get_extent while running xfstests 13 in a loop. This is because fiemap is calling btrfs_get_extent with non-sectorsize aligned offsets, which will end up adding mappings that are not sectorsize aligned, which will cause problems in some cases for subsequent calls to

According to the F.A.Q. there''s a patch to do ratelimiting: http://etudiant.univ-mlv.fr/~jpetazzo/bytelimit.tgz Going with the thought that this is current..I tried it. I wasn''t able to get it to compile, as support for invert was causing a failure(i think). But i was able to get it to compile when I changed line 73 and my box loaded the module. Anyone know if this will do

I noticed that if the free space cache has an error writing out it''s data it won''t actually error out, it will just carry on. This is because it doesn''t check the return value of btrfs_wait_ordered_range, which didn''t actually return anything. So fix this in order to keep us from making free space cache look valid when it really isnt. Thanks, Signed-off-by:

We''ve been keeping around the inode sequence number in hopes that somebody would use it, but nobody uses it and people actually use i_version which serves the same purpose, so use i_version where we used the incore inode''s sequence number and that way the sequence is updated properly across the board, and not just in file write.

From: Wade Cline <clinew@linux.vnet.ibm.com> This patch is only an RFC. My internship is ending and I was hoping to get some feedback and incorporate any suggestions people may have before my internship ends along with life as we know it (this Friday). The filesystem should mount/umount properly but tends towards the explosive side when writes start happening. My current focus is on
