This removes the obsolete argument from nilfs_btnode_submit_block(). This will complete separating a create function of btree node. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Adds a separate routine for creating a btree node block. This is a preparation to reduce the depth of function calls during submitting btree node buffer. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Previously, this function took an status code to return possible error codes. The ("nilfs2: add local variable to cache the number of clean segments") patch removed the possibility to return errors. So, this simplifies the function definition to make it directly return the number of clean segments. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This will hide a function call of nilfs_mdt_clear() in nilfs_mdt_destroy(). This ensures nilfs_mdt_destroy() to do cleanup jobs included in nilfs_mdt_clear(). Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Removes two inline functions: nilfs_mdt_read_inode_direct() and nilfs_mdt_write_inode_direct(). Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
Will displace nilfs_mdt_read_inode_direct function with an individual read method: nilfs_dat_read, nilfs_sufile_read, nilfs_cpfile_read. This provides the opportunity to initialize local variables of each metadata file after reading the inode. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
This will displace nilfs_mdt_new() constructor with individual metadata file constructors like nilfs_dat_new(), new_sufile_new(), nilfs_cpfile_new(), and nilfs_ifile_new(). This makes it possible for each metadata file to have own intialization code. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
This adds an optional "object size" argument to nilfs_mdt_new_common() function; the argument specifies the size of private object attached to a newly allocated metadata file inode. This will afford space to keep local variables for meta data files. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
Previously, nilfs_bmap_add_blocks() and nilfs_bmap_sub_blocks() called mark_inode_dirty() after they changed the number of data blocks. This moves these calls outside bmap outermost functions like nilfs_bmap_insert() or nilfs_bmap_truncate(). This will mitigate overhead for truncate or delete operation since they repeatedly remove set of blocks. Nearly 10 percent improvement was observed for removal of a large file: # dd if=/dev/zero of=/test/aaa bs=1M count=512 # time rm /test/aaa real 2.968s -> 2.705s Further optimization may be possible by eliminating these mark_inode_dirty() uses though I avoid mixing separate changes here. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
Since metadata file routines mark the inode dirty after they successfully changed bmap objects, nilfs_mdt_mark_dirty() calls in nilfs_bmap_add_blocks() and nilfs_bmap_sub_blocks() are redundant. This removes these overlapping calls from the bmap routines. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
lock_buffer() and unlock_buffer() uses in btree.c are eliminable because btree functions gain buffer heads through nilfs_btnode_get(), which never returns an on-the-fly buffer. Although nilfs_clear_dirty_page() and nilfs_copy_back_pages() in nilfs_commit_gcdat_inode() juggle btree node buffers of DAT, this is safe because these operations are protected by a log writer lock or the metadata file semaphore of DAT. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
This lock is eliminable because inodes on the buffer can be updated independently. Although a log writer also fills in bmap data on the on-disk inodes, this update is exclusively done by a log writer lock. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

The current btree lookup routines make a kernel oops when detected inconsistency in btree blocks. These routines should instead return a proper error code because the inconsistency usually comes from corruption of on-disk metadata. This fixes the issue by converting BUG_ON calls to proper error handlings. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Commit 86cf898e ("intel-iommu: Check for 'DMAR at zero' BIOS error earlier.") was supposed to work by pretending not to detect an IOMMU if it was actually being reported by the BIOS at physical address zero. However, the intel_iommu_init() function is called unconditionally, as are the corresponding functions for other IOMMU hardware. So the patch only worked if you have RAM above the 4GiB boundary. It caused swiotlb to be initialised when no IOMMU was detected during early boot, and thus the later IOMMU init would refuse to run. But if you have less RAM than that, swiotlb wouldn't get set up and the IOMMU _would_ still end up being initialised, even though we never claimed to detect it. This patch also sets the dmar_disabled flag when the error is detected during the initial detection phase -- so that the later call to intel_iommu_init() will return without doing anything, regardless of whether swiotlb is used or not.

Doing the strcmp return value as signed char __res = *cs - *ct; is wrong for two reasons. The subtraction can overflow because __res doesn't use a type big enough. Moreover the compared bytes should be interpreted as unsigned char as specified by POSIX. The same problem is fixed in strncmp.
