      "message": "[GFS2] Allow bmap to allocate extents\n\nWe\u0027ve supported mapping of extents when no block allocation is required\nfor some time. This patch extends that to mapping of extents when an\nallocation has been requested. In that case we try to allocate as many\nblocks as are requested, but we might return fewer in case there is\nsomething preventing us from returning the complete amount (e.g. an\nalready allocated block is in the way).\n\nCurrently the only code path which can actually request multiple data\nblocks in a single bmap call is the page_mkwrite path and even then it\nonly happens if there are multiple blocks per page. What this patch does\ndo however, is merge the allocation requests for metadata (growing the\nmetadata tree in either height or depth) with the allocation of the data\nblocks in the case that both are needed. This results in lower overheads\neven in the single block allocation case.\n\nThe one thing which we can\u0027t handle here at the moment is unstuffing. I\nwould like to be able to do that, but the problem which arises is that\nin order to unstuff one has to get a locked page from the page cache\nwhich results in locking problems in the (usual) case that the caller is\nholding the page lock on the page it wishes to map. So that case will\nhave to be addressed in future patches.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

Unfortunately tests\nhave shown that this isn\u0027t enough. If the glock has a demote request\nqueued such that run_queue() in the glock code tries to do a demote when\nits called under readpage then it will try and write out all the dirty\npages which requires locking them. This then deadlocks with the page\nlocked by readpage.\n\nThe solution is to always require two calls into readpage. The first\nunlocks the page, gets the glock and returns AOP_TRUNCATED_PAGE, the\nsecond does the actual readpage and unlocks the glock \u0026 page as\nrequired.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n"

The parameter for zeroing is always\n   KM_USER0 except in one single case that we open code.\n\nAvoiding KM_USER0 makes a lot of code not having to be dealing\nwith the special casing for HIGHMEM anymore. Dealing with\nkmap is only necessary for HIGHMEM configurations. In those\nconfigurations we use KM_USER0 like we do for a series of other\nfunctions defined in highmem.h.\n\nSince KM_USER0 is depends on HIGHMEM the existing zero_user_page\nfunction could not be a macro. zero_user_* functions introduced\nhere can be be inline because that constant is not used when these\nfunctions are called.\n\nAlso extract the flushing of the caches to be outside of the kmap.\n\n[akpm@linux-foundation.org: fix nfs and ntfs build]\n[akpm@linux-foundation.org: fix ntfs build some more]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.
