block: convert to device_add_disk()

2016-06-27T19:26:08Z

For block drivers that specify a parent device, convert them to use device_add_disk(). This conversion was done with the following semantic patch: @@ struct gendisk *disk; expression E; @@ - disk->driverfs_dev = E; ... - add_disk(disk); + device_add_disk(E, disk); @@ struct gendisk *disk; expression E1, E2; @@ - disk->driverfs_dev = E1; ... E2 = disk; ... - add_disk(E2); + device_add_disk(E1, E2); ...plus some manual fixups for a few missed conversions. Cc: Jens Axboe Cc: Keith Busch Cc: Michael S.

mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM

2015-11-07T01:50:42Z

__GFP_WAIT was used to signal that the caller was in atomic context and could not sleep. Now it is possible to distinguish between true atomic context and callers that are not willing to sleep. The latter should clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing __GFP_WAIT behaves differently, there is a risk that people will clear the wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly indicate what it does -- setting it allows all reclaim activity, clearing them prevents it.

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41Z

Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().

block_device_operations->release() should return void

2013-05-07T06:16:21Z

The value passed is 0 in all but "it can never happen" cases (and those only in a couple of drivers) *and* it would've been lost on the way out anyway, even if something tried to pass something meaningful. Just don't bother. Signed-off-by: Al Viro

procfs: new helper - PDE_DATA(inode)

2013-04-09T18:13:32Z

The only part of proc_dir_entry the code outside of fs/proc really cares about is PDE(inode)->data. Provide a helper for that; static inline for now, eventually will be moved to fs/proc, along with the knowledge of struct proc_dir_entry layout. Signed-off-by: Al Viro

ide-cd: signedness warning fix again

2011-06-11T22:06:48Z

One of the legit warnings 'make W=3 drivers/ide/ide-cd.c' generates is: drivers/ide/ide-cd.c: In function ide_cd_do_request drivers/ide/ide-cd.c:828:2: warning: conversion to int from \ unsigned int may change the sign of the result drivers/ide/ide-cd.c:833:2: warning: conversion to int from \ unsigned int may change the sign of the result nsectors is declared int, should be unsigned int. blk_rq_sectors() returns unsigned int, and ide_complete_rq expects unsigned int as well.

block: fix mismerge of the DISK_EVENT_MEDIA_CHANGE removal

2011-06-01T20:29:19Z

Jens' back-merge commit 698567f3fa79 ("Merge commit 'v2.6.39' into for-2.6.40/core") was incorrectly done, and re-introduced the DISK_EVENT_MEDIA_CHANGE lines that had been removed earlier in commits - 9fd097b14918 ("block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers") - 7eec77a1816a ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd") because of conflicts with the "g->flags" updates near-by by commit d4dc210f69bc ("block: don't block events on excl write for non-optical devices") As a result, we re-introduced the hanging behavior due to infinite disk media change reports. Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't do them to hide merge conflicts from me - especially as I'm likely better at merging them than you are, since I do so many merges.
