2021-10-18jfs: use sb_bdev_nr_blocksChristoph Hellwig1-2/+1
Use the sb_bdev_nr_blocks helper instead of open coding it.

2020-06-24block: move struct block_device to blk_types.hChristoph Hellwig1-0/+1
Move the struct block_device definition together with most of the block layer definitions, as it has nothing to do with the rest of fs.h. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

filemap_fdatawait/filemap_write_and_wait may fail, so check the return value and jump to error_out in the case of error. Signed-off-by: Quorum Laval <quorum.laval@gmail.com> Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
2013-06-05jfs: Update jfs_errorJoe Perches1-1/+1
Use a more current logging style. Add __printf format and argument verification. Remove embedded function names from formats. Add %pf, __builtin_return_address(0) to jfs_error. Add newlines to formats for kernel style consistency. (One format already had an erroneous newline) Coalesce formats and align arguments.

2010-04-16jfs: fix diAllocExt error in resizing filesystemBill Pemberton1-1/+5
Resizing the filesystem would result in an diAllocExt error in some instances because changes in bmp->db_agsize would not get noticed if goto extendBmap was called.

2006-01-08[PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi1-2/+1
This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+537
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
