Now that gfs2_quota_sync can be potentially called from multiple threads, we should protect this bit of code, and the sync generation number in particular in order to ensure that there are no races when syncing quotas.

There should be no functional change bar the removal of a test of the MS_READONLY flag which would never be reachable. This merges the common code from qd_fish and qd_trylock into a single function and calls it from both those places.

There is no need for a paramater which relates to the internals of quota to be exposed to users. The only possible use would be to turn it up so large that the memory allocation fails. So lets remove it and set it to a sensible value which ensures that we don't ask for multipage allocations. Currently the size of struct gfs2_holder means that the caluclated value is identical to the previous default value, so there should be no functional change.

When setting the starting point for block allocation, there were calls to both gfs2_rbm_to_block() and gfs2_rbm_from_block() in the common case of there being an active reservation. The gfs2_rbm_from_block() function can be quite slow, and since the two conversions were effectively a no-op, it makes sense to avoid them entirely in this case. There is no functional change here, but the code should be a bit more efficient after this patch. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This patch adds a structure to contain allocation parameters with the intention of future expansion of this structure. The idea is that we should be able to add more information about the allocation in the future in order to allow the allocator to make a better job of placing the requests on-disk. There is no functional difference from applying this patch. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The reservation for an inode should be cleared when it is truncated so that we can start again at a different offset for future allocations. We could try and do better than that, by resetting the search based on where the truncation started from, but this is only a first step. In addition, there are three callers of gfs2_rs_delete() but only one of those should really be testing the value of i_writecount. While we get away with that in the other cases currently, I think it would be better if we made that test specific to the one case which requires it.

Since the previous patch eliminated bi in favor of bii, this follow-on patch needed to be adjusted accordingly. Here is the revised version. This patch adds a new function, gfs2_rbm_incr, which increments an rbm structure. This is more efficient than calling gfs2_rbm_to_block, incrementing, then calling gfs2_rbm_from_block.

This is a respin of the original patch. As Steve pointed out, the introduction of field bii makes it easy to eliminate bi itself. This revised patch does just that, replacing bi with bii. This patch adds a new field to the rbm structure, called bii, which is an index into the array of bitmaps for an rgrp. This replaces *bi which was a pointer to the bitmap. This is being done for further optimizations. Signed-off-by: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

When we used try locks for rgrps on block allocations, it was important to clear the flags field so that we used a blocking hold on the glock. Now that we're not doing try locks, clearing flags is unnecessary, and a waste of time. In fact, it's probably doing the wrong thing because it clears the GL_SKIP bit that was set for the lvb tracking purposes.

This patch introduces a new field in the bitmap structure called bi_blocks. Its purpose is to save us from constantly multiplying bi_len by the constant GFS2_NBBY.

In function gfs2_rbm_from_block, it starts by checking if the block falls within the first bitmap. It does so by checking if the rbm's offset is less than (rbm->bi->bi_start + rbm->bi->bi_len) * GFS2_NBBY. However, the first bitmap will always have bi_start==0. Therefore this is an unnecessary calculation in a function that gets called billions of times. This patch removes the reference to bi_start.

Matt found that commit 27a7c642 ("partitions/efi: account for pmbr size in lba") caused his GPT formatted eMMC device not to boot. The reason is that this commit enforced Linux to always check the lesser of the whole disk or 2Tib for the pMBR size in LBA. While most disk partitioning tools out there create a pMBR with these characteristics, Microsoft does not, as it always sets the entry to the maximum 32-bit limitation - even though a drive may be smaller than that[1]. Loosen this check and only verify that the size is either the whole disk or 0xFFFFFFFF. No tool in its right mind would set it to any value other than these.

The LRU list changes interacted badly with our nr_dentry_unused accounting, and even worse with the new DCACHE_LRU_LIST bit logic. This introduces helper functions to make sure everything follows the proper dcache d_lru list rules: the dentry cache is complicated by the fact that some of the hotpaths don't even want to look at the LRU list at all, and the fact that we use the same list entry in the dentry for both the LRU list and for our temporary shrinking lists when removing things from the LRU. The helper functions temporarily have some extra sanity checking for the flag bits that have to match the current LRU state of the dentry. We'll remove that before the final 3.12 release, but considering how easy it is to get wrong, this first cleanup version has some very particular sanity checking.

由 Sachin Prabhu 提交于
When reading a single page with cifs_readpage(), we make a call to fscache_read_or_alloc_page() which once done, asynchronously calls the completion function cifs_readpage_from_fscache_complete(). This completion function unlocks the page once it has been populated from cache. The module then attempts to unlock the page a second time in cifs_readpage() which leads to warning messages. In case of a successful call to fscache_read_or_alloc_page() we should skip the second unlock_page() since this will be called by the cifs_readpage_from_fscache_complete() once the page has been populated by fscache. With the modifications to cifs_readpage_worker(), we will need to re-grab the page lock in cifs_write_begin(). The problem was first noticed when testing new fscache patches for cifs. https://bugzilla.redhat.com/show_bug.cgi?id=1005737Signed-off-by: NSachin Prabhu <sprabhu@redhat.com> Reviewed-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.com>
