Age	Commit message (Collapse)	Author
2019-06-11	separate source into kernel/ user/ mkfs/	Robert Morris

2019-06-06	gdb backtraces: -ggdb, -fno-omit-frame-pointer, BSIZE=1024	Robert Morris

2019-06-04	support read() and write() bigger than one page	Robert Morris

2016-09-02	Fix a few lines that runoff is complaining about that they are too long	Frans Kaashoek

2016-08-25	Remove trailing white space with:	Frans Kaashoek
	for f in .{h,c}; do sed -i .sed 's/[[:blank:]]$//' $f; done (Thanks to Nicolás Wolovick)
2015-06-27	Pick up where i left off in april:	Frans Kaashoek
	- move log into metadata part of disk, so that marking that the log's blocks are in use falls out for free - superblock describes the whole disk (sizes and offets) - sizes and offsets are computed in one place (mkfs) and the rest of the code refers to the superblock for these values, instead of recomputing them.
2015-04-10	One ide command for nsector_per_block generates nsector_per_block interrupts,	Frans Kaashoek
	instead of 1. ideintr() should wait for nsector_per_block interrupts before waking up the reader; now it wakes up the reader after 1 interrupt, which apparently means that the first sector is available of the command instead of all. For now keep BSIZE to 512.
2015-04-03	Disentangle block size from the disk's sector size. Set block size to 1024 ↵	Frans Kaashoek
	to show that they can be different. Clean up mkfs, simplifying specifying fs parameters, remove some redundancy between fs and mkfs, and fix disk layout bugs. Call blocks in the file system blocks instead of sectors. Passes usertests for different block sizes.
2011-10-11	clarify some FS comments	Robert Morris
