| 2016-09-11 | Straight replacement of B_BUSY with a sleeping lock. | Frans Kaashoek | 1 | -2/+3 | |
| 2016-08-25 | Remove trailing white space with: | Frans Kaashoek | 1 | -11/+11 | |
| for f in *.{h,c}; do sed -i .sed 's/[[:blank:]]*$//' $f; done (Thanks to Nicolás Wolovick) | |||||
| 2016-08-18 | Small change to support RWMUL and WRMUL. Now xv6 truly works with a block size | Frans Kaashoek | 1 | -3/+7 | |
| that is a multiple of the sector size. | |||||
| 2015-04-10 | check blockno passed to idestart | Frans Kaashoek | 1 | -1/+3 | |
| 2015-04-03 | Disentangle block size from the disk's sector size. Set block size to 1024 ↵ | Frans Kaashoek | 1 | -7/+13 | |
| 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. | |||||
| 2012-08-28 | make the book happy | Robert Morris | 1 | -2/+2 | |

| 2011-08-29 | Revert "Introduce and use sleeplocks instead of BUSY flags" | Frans Kaashoek | 1 | -1/+1 | |
| My changes have a race with re-used bufs and the code doesn't seem to get shorter Keep the changes that fixed ip->off race This reverts commit 3a5fa7ed9020eaf8ab843a16d26db7393b2ec072. Conflicts: defs.h file.c file.h | |||||
| 2011-08-26 | Introduce and use sleeplocks instead of BUSY flags | Frans Kaashoek | 1 | -1/+1 | |
| Remove I_BUSY, B_BUSY, and intrans defs and usages One spinlock per buf to avoid ugly loop in bget fix race in filewrite (don't update f->off after releasing lock) | |||||

| 2011-07-29 | Map kernel high | Frans Kaashoek | 1 | -0/+1 | |

| 2011-01-11 | make new code like old code | Russ Cox | 1 | -2/+2 | |
| Variable declarations at top of function, separate from initialization. Use == 0 instead of ! for checking pointers. Consistent spacing around {, *, casts. Declare 0-parameter functions as (void) not (). Integer valued functions return -1 on failure, 0 on success. | |||||
