block: remove genhd.h

2022-02-02T14:49:59+00:00

There is no good reason to keep genhd.h separate from the main blkdev.h header that includes it. So fold the contents of genhd.h into blkdev.h and remove genhd.h entirely.

nfsd/blocklayout: use ->get_unique_id instead of sending SCSI commands

2021-10-22T14:33:57+00:00

Call the ->get_unique_id method to query the SCSI identifiers. This can use the cached VPD page in the sd driver instead of sending a command on every LAYOUTGET. It will also allow to support NVMe based volumes if the draft for that ever takes off. Signed-off-by: Christoph Hellwig Acked-by: J.

block: remove REQ_OP_SCSI_{IN,OUT}

2021-06-30T21:34:19+00:00

With the legacy IDE driver gone drivers now use either REQ_OP_DRV_* or REQ_OP_SCSI_*, so unify the two concepts of passthrough requests into a single one. Reviewed-by: Chaitanya Kulkarni Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: remove unnecessary argument from blk_execute_rq

2021-01-25T04:52:39+00:00

We can remove 'q' from blk_execute_rq as well after the previous change in blk_execute_rq_nowait. And more importantly it never really was needed to start with given that we can trivial derive it from struct request.

block: add a bdev_is_partition helper

2020-09-25T14:18:57+00:00

Add a littler helper to make the somewhat arcane bd_contains checks a little more obvious. Signed-off-by: Christoph Hellwig Acked-by: Ulf Hansson Signed-off-by: Jens Axboe

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

nfsd: use 64-bit seconds fields in nfsd v4 code

2019-07-03T21:52:09+00:00

After commit 95582b008388 "vfs: change inode times to use struct timespec64" there are spots in the NFSv4 decoding where we decode the protocol into a struct timeval and then convert that into a timeval64. That's unnecesary in the NFSv4 case since the on-the-wire protocol also uses 64-bit values. So just fix up our code to use timeval64 everywhere. Signed-off-by: J. Bruce Fields

Pull inode timestamps conversion to timespec64 from Arnd Bergmann: "This is a late set of changes from Deepa Dinamani doing an automated treewide conversion of the inode and iattr structures from 'timespec' to 'timespec64', to push the conversion from the VFS layer into the individual file systems. As Deepa writes: 'The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions' Thomas Gleixner adds: 'I think there is no point to drag that out for the next merge window. The whole thing needs to be done in one go for the core changes which means that you're going to play that catchup game forever. Let's get over with it towards the end of the merge window'" * tag 'vfs-timespec64' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground: pstore: Remove bogus format string definition vfs: change inode times to use struct timespec64 pstore: Convert internal records to timespec64 udf: Simplify calls to udf_disk_stamp_to_time fs: nfs: get rid of memcpys for inode times ceph: make inode time prints to be long long lustre: Use long long type to print inode time fs: add timespec64_truncate()
