Subject: RFC: untangle and fix __blkdev_issue_discard
Date: Thu,  7 Mar 2024 08:11:47 -0700	[thread overview]
Message-ID: <20240307151157.466013-1-hch@lst.de> (raw)

Hi all,

this tries to address the block for-next oops Chandan reported on XFS.
I can't actually reproduce it unfortunately, but this series should
sort it out by movign the fatal_signal_pending check out of all but
the ioctl path.  The write_zeroes and secure_erase path will need
similar treatment eventually.

Test with blktests and the xfstests discard group for xfs only. Note that
the latter has a pre-existing regression in generic/500 that I'll look
into in a bit.
