      "message": "ext4: Expand extra_inodes space per the s_{want,min}_extra_isize fields \n\nWe need to make sure that existing ext3 filesystems can also avail the\nnew fields that have been added to the ext4 inode. We use\ns_want_extra_isize and s_min_extra_isize to decide by how much we should\nexpand the inode. If EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature is set\nthen we expand the inode by max(s_want_extra_isize, s_min_extra_isize ,\nsizeof(ext4_inode) - EXT4_GOOD_OLD_INODE_SIZE) bytes. Actually it is\nstill an open question about whether users should be able to set\ns_*_extra_isize smaller than the known fields or not.\n\nThis patch also adds the functionality to expand inodes to include the\nnewly added fields. We start by trying to expand by s_want_extra_isize\nbytes and if its fails we try to expand by s_min_extra_isize bytes. This\nis done by changing the i_extra_isize if enough space is available in\nthe inode and no EAs are present. If EAs are present and there is enough\nspace in the inode then the EAs in the inode are shifted to make space.\nIf enough space is not available in the inode due to the EAs then 1 or\nmore EAs are shifted to the external EA block. In the worst case when\neven the external EA block does not have enough space we inform the user\nthat some EA would need to be deleted or s_min_extra_isize would have to\nbe reduced.\n\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Kalpak Shah \u003ckalpak@clusterfs.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n"

      "message": "ext4: Add nanosecond timestamps\n\nThis patch adds nanosecond timestamps for ext4. This involves adding\n*time_extra fields to the ext4_inode to extend the timestamps to\n64-bits.  Creation time is also added by this patch.\n\nThese extended fields will fit into an inode if the filesystem was\nformatted with large inodes (-I 256 or larger) and there are currently\nno EAs consuming all of the available space. For new inodes we always\nreserve enough space for the kernel\u0027s known extended fields, but for\ninodes created with an old kernel this might not have been the case. So\nthis patch also adds the EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature\nflag(ro-compat so that older kernels can\u0027t create inodes with a smaller\nextra_isize). which indicates if the fields fitting inside\ns_min_extra_isize are available or not.  If the expansion of inodes if\nunsuccessful then this feature will be disabled.

      "message": "[PATCH] ext[34]: EA block reference count racing fix\n\nThere are race issues around ext[34] xattr block release code.\n\next[34]_xattr_release_block() checks the reference count of xattr block\n(h_refcount) and frees that xattr block if it is the last one reference it.\n Unlike ext2, the check of this counter is unprotected by any lock.\next[34]_xattr_release_block() will free the mb_cache entry before freeing\nthat xattr block.  There is a small window between the check for the re\nh_refcount \u003d\u003d1 and the call to mb_cache_entry_free().  During this small\nwindow another inode might find this xattr block from the mbcache and reuse\nit, racing a refcount updates.  The xattr block will later be freed by the\nfirst inode without notice other inode is still use it.  Later if that\nblock is reallocated as a datablock for other file, then more serious\nproblem might happen.\n\nWe need put a lock around places checking the refount as well to avoid\nracing issue.  Another place need this kind of protection is in\next3_xattr_block_set(), where it will modify the xattr block content in-\nthe-fly if the refcount is 1 (means it\u0027s the only inode reference it).\n\nThis will also fix another issue: the xattr block may not get freed at all\nif no lock is to protect the refcount check at the release time.  It is\npossible that the last two inodes could release the shared xattr block at\nthe same time.  But both of them think they are not the last one so only\ndecreased the h_refcount without freeing xattr block at all.\n\nWe need to call lock_buffer() after ext3_journal_get_write_access() to\navoid deadlock (because the later will call lock_buffer()/unlock_buffer\n() as well).\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
